Re: Surely
FWIW - In Arizona as in most (all?) of the US, you aren't supposed to mow pedestrians down even if the pedestrians shouldn't be in the road.
Relevant law: per https://activerain.com/blogsview/1497199/watch-where-you-re-walking-arizona-revised-statutes-pedestrian-right-of-way
28-794. Drivers to exercise due care
Notwithstanding the provisions of this chapter every driver of a vehicle shall:
1. Exercise due care to avoid colliding with any pedestrian on any roadway.
2. Give warning by sounding the horn when necessary.
3. Exercise proper precaution on observing a child or a confused or incapacitated person on a roadway.
It doesn't surprise me that Uber's "autonomous" vehicle doesn't seem to comply with relevant traffic laws. Bunch of greedy sociopaths if you ask me. Likewise Tesla. Waymo OTOH seems to be run by adults. If you ask me, Uber, Tesla, et. al. vehicles should be required to be led by someone on foot waving a red flag or a lantern (see https://en.wikipedia.org/wiki/Red_flag_traffic_laws) until such time as they demonstrate reasonable concern for public safety.
