That's the key question: whose laws are Waymo enforcing? ICE and Flock's extra-constitutional policies? City ordinances? A future eco-radical government's laws?
How about things taking place outside the car?
Can Waymo mount a robotic machine gun next to the LIDAR and snipe suspected terrorists? Release tear gas? Self destruct, killing several nuns to protect s CEO?
Yes? I am pretty sure they don't do algorithmic policing. Fwiw, they probably don't do any policing, but that is a different subject.
I am not against monitoring for safety - I am against deploying a sophisticated network of automated monitoring that covers all digital and soon physical aspects of my life for my "safety" by for profit companies.
