It appears so. The Wall Street Journal article from October:
Robotaxis Can’t Be a Solo Act

Networks of expensive, self-driving cars need a wide base of paying riders, which could make Uber essential to Tesla’s success…While robotaxis spare the expense of paying a human driver, they are far from cheap. Analysts from Bernstein estimate that Waymo’s driverless cars cost between $150,000 and $200,000 a piece, factoring in the cost of the vehicle itself and the sensors and computing power necessary to run them.
So it seems rioters figured out that if you order one to come pick you up in a riot zone, and you throw something at it to make it think it hit something, it stops cold. In this case, when half a dozen are ordered to roughly the same spot, and all are stopped, they become toxic tiki torches.
