> If the speed limit was 15 mph, and the Waymo vehicle was traveling at 17 mph before braking, why do you believe the Waymo vehicle would honor a 12 mph speed limit?

+/- 2 mph is acceptable speedometer and other error. (15 mph doesn’t mean never exceed under any legal inteprerstion I know.)

It’s reasonable to say Waymo would reduce speed in a 12 versus 15 in a way most humans would not.
