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.
