It's Uber. They don't think critically. Their QC probably introduced #1 to "protect the uber experience".
You're joking, but that's actually true. One part of the development process involves tuning the collision avoidance system to not be "jumpy", which would make the ride uncomfortable.
(That they still set it up in a way that leaves the car unable to avoid a collision it definitely knows is going to happen
is really baffling though)
