Perhaps, like the uber/lyft light-on signage, when FSD is engaged some sort of visual cue should activated on the exterior of the vehicle. It can be subtle like an extra set of LEDs eliminated either on the front or back. The end effect might be that other drivers will make it more predicable for FSD to safely navigate.

But I as one of other drivers should not have to change my driving habits just for elon to make more money.
