What the hell even is the point mandating a back up alarm for self driving cars ? Backup alarms literally only exist because visibility to the rear is worse, and to warn pedestrians that a vehicle nearby is moving with very poor to no visibility, but that only applies to human operated vehicles. Autonomous vehicles use 360° sensors, they can "see" just as well in reverse as in forward. Be that good or bad, it's equal in every direction, so mandating an alarm just for reverse seems enormously pointless. Especially since the cars tend to be slower in reverse, so if anything it's less necessary then, vs. when they're moving forward.
Fixxd: Back up alarm turned into active drive alarm.
