Cruise hits, runs over, and drags pedestrian, severely injuring them

The Incident

On October 2nd 2023 at 9:30pm a pedestrian in San Francisco crossed 5th Street at Market Street in the crosswalk as the light turned red. The pedestrian was first hit by a human-driven Sentra vehicle, remained on the hood for a distance, and then fell into the adjacent lane. A Cruise robotaxi, named “Panini”, traveling in the adjacent right-hand lane, hit the pedestrian and stopped. The Cruise vehicle then proceeded another 20 feet, dragging the pedestrian underneath the vehicle, and stopped with a rear wheel on top of the person. The pedestrian was severely injured by this motion of the Cruise robotaxi. A passerby reported the crash via 911 (Cruise did not). The Fire Department arrived within minutes and lifted the car to remove the pedestrian. They were taken to SF General Hospital in critical condition, and spent approximately 2 months there, an extremely long time to be hospitalized.

Cruise did not initially inform regulators nor the public about the Cruise robotaxi dragging and seriously injuring the pedestrian. Because of their lack of transparency Cruise received a cease and desist letter from the DMV declaring their vehicles to be unsafe and ordering them to immediately halt autonomous driving for all of California. The CPUC repealed Cruise’s permit to handle passengers. Cruise stopped service throughout the country.

The handling of the incident caused the founders of Cruise to resign. GM fired an additional 9 executives. 900 employees were laid off. Though roughly $15B has been invested in Cruise it does not appear they have a viable plan for recovering.

Purpose of Report

This report was created to determine the current safety of the Cruise Automated Driving System, especially with respect to pedestrians, and how it could be improved upon. It is unaffiliated both with Cruise and the regulators in order to not be biased.

This report was completed on 1/23/2024, before additional information was made available by Cruise when they publicly released their Quinn Emanuel report along with the Exponent technical analysis. This meant that many of the facts, such as the vehicle not being able to do a pullover maneuver, had to be deduced from photos and other evidence. Separately, an analysis of the Quinn Emanuel report will also be published here.

In no way is this report deflecting blame from behavior of human driver of the Sentra vehicle who first hit the pedestrian. There is no doubt about the culpability of the human driver, nor that their behavior was illegal and deplorable. Additional research into the driver is therefore not needed. It is now simply a matter for our legal justice system.

But fault is not assigned to just an individual party. It is assigned to whoever contributed to the outcome. We need to understand if Cruise ADS was also at fault, and if so, by how much. We also need to understand any issues with how Cruise communicated both with the regulators and the public.

News Reports

The immediate news reports the night of 10/2/23 indicated that a pedestrian was hit by a Cruise vehicle. The next day, 10/3/23, Cruise was able to change the narrative by emphasizing that the pedestrian was first hit by a human-driven car and that the Cruise vehicle was blameless.

Then the morning of 10/6/23 the key story was published in Forbes by Cyrus Farivar, Cruise Robotaxi Dragged Woman 20 Feet In Recent Accident, Local Politician Says. The author of this analysis, Michael Smith, had gathered information, determined the true circumstances of the crash, and provided the information to Farivar so that he could to confirm the situation and write the news story that showed that Cruise was not being transparent. This completely changed the narrative. The result was that the DMV and the CPUC suspended Cruise autonomous service, and now it appears that Cruise has no way to recover.

San Francisco Supervisor Aaron Peskin now says that while the robotaxi may have attempted to avoid hitting her, the AV “dragged her underneath the car for approximately 20 feet, which was the source of her major injuries.”

Phil Koopman is a leading expert on autonomous vehicles safety and teaches at Carnegie Mellon University. His extensive writings on the subject can be found at Safe Autonomy.

Koopman makes the important points that the Cruise vehicle did not exercise due care and slow down when a pedestrian was hit by another vehicle, that it wrongly executed a “pull over” maneuver, that Cruise did not call 911 for a serious injury, and that Cruise focused on blaming others instead of focusing on safety.

Templeton was able to view the video from the Cruise vehicle, showing the crash. His key point is that the Cruise vehicle did not a handle complicated situation of a pedestrian ending up under the vehicle, and moved forward as a result. Plus the Cruise should have slowed down when it first detected the dangerous situation of the pedestrian crossing against the light. Templeton also emphasizes that Cruise crossed the line by not being transparent and only putting out good news

Analysis by Robotaxi.rodeo

Some statements have been made about the crash that are either inconsistent or conflict with the evidence. Therefore the first step is to determine certain details conclusively. Then can we determine what exactly went wrong and also where statements by Cruise have not been truthful.

Statements by Cruise

These statements were taken from Cruise’s blog posts and tweets.

A Cruise AV named Panini, operating in driverless autonomous mode, was at a complete stop at a red light. A human-driven vehicle was stopped in the adjacent lane to the left of the AV. The Cruise vehicle detected that the pedestrian crossing 5th Street in the crosswalk, as the light had turned red. The pedestrian had cleared the lane of the Cruise vehicle. Both vehicles started crossing while the pedestrian was still in the crosswalk. The human-driven vehicle struck the pedestrian. The initial impact was severe and launched the pedestrian directly in front of the Cruise AV. The AV biased rightward before braking aggressively, but still made contact with the pedestrian. The AV detected a collision, bringing the vehicle to a stop; then attempted to pull over to avoid causing further road safety issues, pulling the individual forward approximately 20 feet.

Was initial impact severe and “launch” the pedestrian?

The first obvious issue is that the vehicle came to a stop quite far away from the crosswalk. Key question is how did the pedestrian travel so far given that Cruise claims the initial impact when pedestrian was in the crosswalk was severe and the pedestrian was launched in front of the AV? Something is not right. All sources agree that the pedestrian was initially hit while in the crosswalk so that part is not in dispute.

Given that the pedestrian travelled 80 feet after being hit by the human-driver in the crosswalk to when they were hit by the Cruise vehicle, it is clear that the pedestrian was not immediately “launched” into the path of the Cruise. The Automotive News article, where the reporter viewed the video from the Cruise vehicle, clearly indicates what did actually happen:

While staying in the left lane, the adjacent vehicle accelerated faster than the robotaxi. As a result, it was about a car length ahead when it struck the pedestrian. The woman was stuck atop the car’s hood for about two to three seconds as the driver continued down the street.

The victim, whose name has not been released, then fell from the first car’s hood onto the road and into the path of the oncoming robotaxi. She was on the ground for little more than a second before being struck [by the Cruise].

Automotive News 10/4/23 6:32 AM

The human-driven vehicle hit the pedestrian with small enough force that they remained on the hood of the car for 2-3 seconds. Then the victim simply fell off of the hood into the path of the robotaxi. There was no severe impact and there was no launching.

Therefore the Cruise statement “The initial impact was severe and launched the pedestrian directly in front of the Cruise AV” is indisputably incorrect and very misleading.

Did the Cruise vehicle stop as quickly as possible?

Cruise blog post stated “The AV biased rightward before braking aggressively, but still made contact with the pedestrian.” While Cruise made this statement to convey that the vehicle behaved as safely as possible, it actually belies that the vehicle should have detected the dangerous situation in advance and slowed down or even stopped. Driving in this defensive way would have provided the vehicle to completely avoid hitting the pedestrian when they were in the path of travel.

Cruise acknowledges that the vehicle detected the pedestrian still being in the intersection when the traffic signal turned green. The video from the Cruise vehicle shown to news agencies and to regulators clearly showed a problem, that the pedestrian could be, and then was hit by the human-driven Sentra. Even if the pedestrian was not detected after the initial crash, the autonomous driving system should have had what is termed “object permanence” in order to understand that there was a person in a very risky situation, demanding cautious behavior.

It should also be noted that since we have concluded that the pedestrian did not end up in the path of the Cruise for several seconds (see above), it is clear that the Cruise driving system had plenty of time to detect that there was a problem and to slow down or even stop proactively.

Vehicle Code pertaining to situation

The California Vehicle Code specifies a minimum for safety. An autonomous vehicle driving system must meet this minimum, but would hopefully take even more precaution. California Vehicle Code 21950 clearly indicates that the driver must exercise due care and shall reduce speed to safeguard the safety of the pedestrian.

CHAPTER 5. Pedestrians’ Rights and Duties

21950.  

(a) The driver of a vehicle shall yield the right-of-way to a pedestrian crossing the roadway within any marked crosswalk or within any unmarked crosswalk at an intersection, except as otherwise provided in this chapter.

(b) This section does not relieve a pedestrian from the duty of using due care for their safety. No pedestrian may suddenly leave a curb or other place of safety and walk or run into the path of a vehicle that is so close as to constitute an immediate hazard. No pedestrian may unnecessarily stop or delay traffic while in a marked or unmarked crosswalk.

(c) The driver of a vehicle approaching a pedestrian within any marked or unmarked crosswalk shall exercise all due care and shall reduce the speed of the vehicle or take any other action relating to the operation of the vehicle as necessary to safeguard the safety of the pedestrian.

(d) Subdivision (b) does not relieve a driver of a vehicle from the duty of exercising due care for the safety of any pedestrian within any marked crosswalk or within any unmarked crosswalk at an intersection.

(e) (1) A peace officer, as defined in Chapter 4.5 (commencing with Section 830) of Title 3 of Part 2 of the Penal Code, shall not stop a pedestrian for a violation of this section unless a reasonably careful person would realize there is an immediate danger of a collision with a moving vehicle or other device moving exclusively by human power.

(e) (2) This subdivision does not relieve a pedestrian from the duty of using due care for their safety.

(e) (3) This subdivision does not relieve a driver of a vehicle from the duty of exercising due care for the safety of any pedestrian within the roadway.

California Vehicle Code 21950

But even though the pedestrian was in a precarious position and then was hit by the adjacent vehicle, the Cruise vehicle never responded accordingly by slowing down or stopping for safety.

A key part of both Koopman’s and Templeton’s analysis of the crash was that the Cruise vehicle should have immediately driven more cautiously, before the human-driven Sentra even collided with the pedestrian, in order to avoid itself colliding with the pedestrian further down the road.

The NHTSA Investigation into autonomous Cruise vehicles and pedestrian safety further reinforces that the Cruise vehicle did not behave in safe way and did not exhibit due caution as required by the vehicle code.

The conclusion is that the Cruise system did not react appropriately nor legally to an obviously dangerous situation where a pedestrian was still in the crosswalk when the traffic signal turned green. Because the Cruise vehicle did not stop or at least slow down it was traveling too fast for the dangerous condition and then did not have enough time to brake before hitting the pedestrian that ended up in its path. Cruise making a claim that its vehicle did all that it could and braked aggressively was very misleading because it ignored that their vehicle could have avoided hitting the pedestrian if had been programmed to drive more defensively.

Isn’t the human driver of the Sentra solely at fault?

The human-driven Sentra was the first vehicle to hit the pedestrian. If they had not hit the pedestrian, pushing them into the path of the Cruise, then the Cruise would not have hit and then dragged the pedestrian. The driver also left a seriously wounded pedestrian behind, which is simply despicable. Some people, including spokespeople for Cruise, use these facts to assign full fault to the human driver of the Sentra and maintain that the Cruise vehicle is blame free.

But that is not how fault works. It isn’t just the instigator who is at fault. Multiple parties can be at fault at the same time. Fault is apportioned between those parties depending on the situation. And it should be noted that if the Cruise vehicle was not there at the time, the pedestrian would not have suffered traumatic injuries by being hit, dragged 20 feet, and then pinned underneath the almost two-ton vehicle.

San Francisco Supervisor Aaron Peskin now says that while the robotaxi may have attempted to avoid hitting her, the AV “dragged her underneath the car for approximately 20 feet, which was the source of her major injuries.”

Forbes 10/6/23

Being the second vehicle to hit a pedestrian doesn’t absolve the driver of operating carelessly around pedestrians. Vehicle Code 21950 should still have been adhered to, at a very minimum.

The human-driver is only partially at fault since the worst traumatic injuries appear to be caused by unsafe behavior of the Cruise vehicle.

Did the Cruise perform a pull-over maneuver for safety?

After first not acknowledging and withholding evidence that the Cruise vehicle continued forward and dragged the pedestrian for roughly 20 feed, Cruise claimed that it continued forward for “safety” reasons.

The AV biased rightward before braking aggressively, but still made contact with the pedestrian. The AV detected a collision, bringing the vehicle to a stop; then attempted to pull over to avoid causing further road safety issues.

After a collision, Cruise AVs are designed to perform a maneuver to minimize the safety risks to the extent possible within the driving context. This is called achieving a minimal risk condition, and it’s required under California regulations and encouraged under Federal AV guidance. The specific maneuver, such as coming to an immediate stop, pulling over out of lane of travel, or pulling out of traffic after exiting an intersection, is highly dependent on the driving context as well as the Cruise AV’s driving capabilities in the moment.

Cruise Blog Post 10.24.23 (since removed)

But images from the scene clearly show a very different situation. There was no area for the vehicle to pull over since it was next to a separated bike lane that extended for quite a distance. Also, there are four lanes of car travel where the collision occurred, meaning that the vehicle was not risk of blocking emergency responders, and that there was no possible benefit of pulling over. And most importantly, even after it did the “pull-over maneuver” and drove forward 20 feet, dragging and injuring the pedestrian, the vehicle ended up further away from the curb, not closer to it.

All of the factors mentioned above that made it impossible to pull out of traffic were known by the Cruise Automated Driving System. There is no excuse for making the dangerous move, dragging the pedestrian. It had all the necessary information, yet it somehow made the absolute wrong decision.

There is also the separate issue that the Cruise vehicle detected the pedestrian in the roadway. That is why it braked aggressively. And Cruise stated that the vehicle detected a collision. This clearly indicated that something was very wrong, even if the exact nature of the problem could not be identified. There was a significant risk that a person was in the roadway and this possibility should have precluded any kind of maneuvering. Yet the vehicle still moved ahead 20 feet.

The Cruise vehicle did not and could not pull over in order to be out of the way of emergency responders. There was no room for the vehicle to pull over because of the presence of the separated bike lane. And the vehicle had not pulled over any closer to the curb after dragging the pedestrian forward for 20 feet. Given the four-lane road. emergency vehicles vehicles would have not been blocked. And the Cruise vehicle should not have moved forward because it had just been in a collision with an object that could have been a person. The maneuver was completely inappropriate and indicates that the Cruise ADS had serious flaws.

How well did Cruise respond to the emergency?

Cruise has stated that the vehicle detected the pedestrian in the roadway and braked aggressively. They also stated the vehicle detected that a collision had occurred. The problem with the vehicle then doing a pull-over maneuver was covered above. The other key problem was that they never contacted emergency services via 911. In fact, it was emergency services that contacted them, to tell them to not allow the vehicle to move any further. Fortunately. a passerby called 911 and then helped to comfort the victim until the police arrived. That the victim was pinned under an almost 2-ton Cruise (EVs are quite heavy and the battery alone weighs 947 lb) for a 10 or more minutes is already a serious problem. But them not immediately contacting emergency services indicates a serious flaw with driverless vehicles. There will be situations where a bystander doesn’t happen to be around. This is also a key point that Koopman made in his analysis of the crash.

It should also be noted that Anthony’s analysis contends that Cruise has a weakness for handling emergency situations due to financial pressures. Emergency situations are inherently complicated, but Cruise had to focus its efforts on generating revenue as soon as possible. Therefore handling complicated emergency situations was not adequately addressed in advance.

Very poor reaction to an emergency situation. The vehicle moved after detecting colliding with the pedestrian, dragging and greatly injuring them. And Cruise never called 911.

Did Cruise withhold critical information?

The CPUC filed declarations attesting to how Cruise did not initially nor proactively provide adequate details, particularly that the pedestrian was dragged 20 feet after being hit by the Cruise vehicle. And the DMV has provided the initial email from Cruise that fails to mention the pedestrian being dragged.

Cruise also repeatedly mischaracterized important issues such as the initial impact of the human-driven Sentra was “severe” and that the pedestrian was “launched” in front of the Cruise, when actually the process occurred over several seconds.

Cruise also mischaracterized that after initially hitting the pedestrian that the Cruise needed to do a “pull-over maneuver” for “safety” when it did not, should not, and could not have done so.

Cruise first covered up the maneuver and the dragging of the pedestrian, and they have continued to mischaracterize virtually all critical parts of the crash. Their behavior has been nothing less than dishonest and atrocious.

Has Cruise become more transparent?

After the October 2nd crash and resulting fallout, Cruise has pledged to be more transparent and to work with the community. They did remove from the company most of the people who were responsible for the Cruise response to the crash. Unfortunately it appears that they are not living up to their new commitments.

They still are pushing the false “pull-over maneuver” narrative to make it appear that the vehicle was trying to do the safest thing. In addition, they will no longer provide access to journalists to the video of the crash, which means that further investigations are hampered. And though repeatedly asked Cruise for information in order to help pedestrian advocacy organizations develop their policies with respect to AVs, they only followed up once and never provided any actual information.

Another issue, as noted in Brad Templeton’s analysis, is that no information ever comes out publicly from victims of Cruise mishaps. The consistency of no information coming out could mean that victims are paid by Cruise to not speak publicly via a non-disclosure agreement. At a very minimum, Cruise should tell regulators and the public if they are paying affected parties for non-disclosure agreements. And if they have entered into non-disclosure agreements with victims then they should cancel them to achieve true transparency and so that regulators can assure that needed safety improvements are actually made.

No, they do not appear to now be more transparent.

Other information needed?

Key piece of information is to understand how long the pedestrian was pinned under the very heavy Cruise vehicle. This cannot be determined unless Cruise allows access to additional information including the police incident report, related 911 call logs, and timestamped video from the vehicle. Though asked, they are not making such information available.

A complete analysis also needs to know the portion of the serious injuries that were caused by the Cruise hitting and then dragging the victim, compared to by the initial impact of the human-driven Sentra. But this cannot be determined unless Cruise provides additional information.

The Untruths by Cruise

Cruise did not just play loose with a few details. Their untruths were numerous, blatant, and very problematic. Since their software recall was based on the untruth that the root cause was the vehicle doing a pull-over maneuver (root cause was actually that the robotaxi proceeded from the light incautiously) they never actually fixed the key safety issue.

The most important of the Cruise untruths are:

  • That they proactively provided information to regulators that the pedestrian was dragged 20 feet and seriously injured by the Cruise robotaxi
  • That the robotaxi braked as soon as possible when actually it should have instead braked earlier, at the intersection, as soon as pedestrian was at risk
  • That the robotaxi did a “pull-over maneuver” for “safety”

Additional Cruise untruths include:

  • That they provided all information immediately when asked, including the full video, to the DMV and CPUC
  • That initial impact by human-driven vehicle was “severe”
  • That the pedestrian was suddenly “launched” into path of the Cruise robotaxi
  • That their Cruise vehicle was “not at fault”
  • That they would provide vehicle video to the press (they stopped once word had gotten out that the pedestrian was dragged)
  • That they would now be more transparent
  • That they had a great safety record since incidents are almost always the fault of a human driver

And this incident is not the only time they have been untruthful. When other crashes were examined, Cruise spread falsehoods each time 6/3/2022, 3/23/23, 8/7/23, 8/17/23, and 8/18/23. And Cruise has misrepresented other issues such as accessibility.

Conclusions

Serious injuries to the pedestrian were caused in significant part due to dangerous behavior of the Cruise Automated Driving System. When the pedestrian was first detected by the Cruise vehicle, the Cruise should have exhibited due caution, as specified by California Vehicle Code 21950, and stopped or at least proceeded much more cautiously. The Cruise vehicle would then have easily had the opportunity to stop before hitting the pedestrian, averting causing serious injuries. Their software recall did not address this key issue, which indicates that they were not trying to learn from mistakes and make their system truly safe.

The Cruise vehicle should not have moved after detecting having collided with the pedestrian. The movement was not appropriate because the Cruise vehicle did not have room to pull over, and it did not actually pull over at all even after dragging the pedestrian for 20 feet. In addition, there was no possible benefit to pulling over, even if it was doable, since it was on a four-lane road which meant that emergency service vehicles could not be blocked. This movement should not have been called a “pull-over maneuver” since that is not what the vehicle was doing (it could not!). Describing it as a “pull-over maneuver” only served the purpose of wrongly making the Cruise ADS system appear as trying to have done the best thing, and then getting “fixed” afterwards. It was not the appropriate thing to do, it could not be done, and it gravely injured the pedestrian.

Cruise both withheld information and actively mislead both regulators and the public, whose streets the vehicles were being tested on. And from looking into other crashes, this was a common practice of theirs. This also meant that while focused on blaming others instead of trying to determine what really went wrong, and fixing it. They clearly have had a lack of a safety culture and instead of focused on marketing and “move fast and break things”. This is absolutely unacceptable behavior for a company that was testing 2-ton vehicles on public streets. A disaster was inevitable. Unfortunately, a pedestrian paid the price for Cruise’s actions.
