From the article:
"Initially, Cruise said connectivity issues from a "large event" presumed to be the
Outside Lands music festival caused at least
10 cars to become immobilized, but clarified that instead, a pedestrian interfered with one of the cars, and that the car stopped as it awaited further instructions from a remote advisor.
As the first car stopped, more pedestrians came into contact with the "lead car" which delayed "overall resolution time" further. Other Cruise cars picking up or dropping off riders queued up behind the lead car.
It took around 15 minutes for the autonomous vehicles to continue driving their routes as usual.
Cruise clarified that "limited bandwidth issues" created a lag in their remote advisors' ability to "provide expedient guidance" to several cars.
Many Cruise riders Friday night were festival goers, which created a "higher concentration of [Cruise vehicles] in a congested area." Because of higher-than-normal congestion levels, remote assistance was provided to help navigate.
"Congestion from massive crowds of this size can and did impact our AVs’ ability to maneuver in areas close to Golden Gate Park," Cruise's statement read. "Normally, our remote advisors might have been able to more quickly move our vehicles, but the above data lag combined with enormous pedestrian crowds resulted in several of our cars being moved by our field support teams."

So is Cruise revising their statement to avoid blame?
I feel like the truth might be somewhere in the middle. There might have been some pedestrian interference that contributed to the stop of the lead car but then things got worse as other Cruise vehicles behind the lead car could not proceed and remote assistance was not able to connect quick enough due to the slow data connection.
I have a few thoughts:
1) Did the lead car stop because of malicious interference by pedestrians or simply because of big crowds from the festival?
2) Unfortunately, I am not sure AVs can do much about deliberate interference. And sadly, robotaxis do seem to be the target of malicious interference (for ex: coning).
3) I still think Cruise needs a better contingency plan for when the vehicles lose the data connection.
4) It does feel like Cruise cannot reliably handle large crowd events as large crowds will cause the lead car to stall, since there is a large crowd event there wll be other Cruise vehicles bringing other rides to the event, leading to higher chance of a mass stall event.
