There's a concern about more cameras recording all the time, and while I don't personally buy that argument (because being out in public means you don't have any expectation of privacy) I don't agree with these companies storing that data to give to police, effectively making Waymo or Cruise into private arms of law enforcement.

The reason that makes the most sense to me is it still encourages cities to be designed around cars, and not transit or people-oriented methods of travel. Even though they might make travel smoother by better decision-making than people, I'd still rather see more spaces devoted to foot traffic connected by buses or trains than the sprawl necessitated by personal vehicles.
