If it merely slowed down, it would still be driving illegally. Everywhere I've driven in the USA, if there is a stopped school bus in front of you, or on the other side of the road, all traffic on the road must stop and remain stopped until the school bus retracts the sign and resumes driving.

Point being, if it always slowed down (sign or no sign), then at least reaction time requirements would be lessened.

I mean, it can be programmed in any way, so why not program it to follow both rules: If the sign is extended, then stop. Else if the sign is not extended, slow down.

if(bus) slow

if(bus and sign) stop

Then at least it fails slightly safer.
