I don't see how Volvo is responsible for Uber's recklessness. Volvo didn't make them test on public roads with unsafe technology.

IIRC it was discovered this happened because the owner hadn't purchased the "Pedestrian Avoidance Package".
And shortly before that, a Volvo plowed into a parked truck (in a demo):
This was "was the result of an earlier flat battery that temporarily disabled the system due to low voltage" [0]
The pattern here is not only due to the collision systems themselves, but to the system around the collision avoidance system.
