If they actually cared about safety they'd license it to auto manufacturers and let people roll stop signs when it's safe and warm them when it's not. Or just put cheap traffic lights everywhere to speed up traffic. This is about earning revenue for municipallitues with micro enforcement zones.
(note/edit) I'm talking about flashing lights in the cab like when my car thinks I need to break. Forcing me to break unless I'm about to kill someone. Or just re-thinking the stop sign. The point of stop signs is they're effing cheap. If you're going to put AI cameras on all of them that is no longer cheap, could you not just turn them into lighted intersections that give the green to the right person and remove confusion and detect or have slappers for the pedestrians and just smooth out traffic everywhere? Or is the unsaid thing that stop signs are actually smoother because well you can roll them using your human brain to make decisions?
