> turn signals just telegraph your intent to make a move, giving other drivers valuable milliseconds to block your approach You're thinking of turn signals wrong. Generally you shouldn't be using them as a request, but rather a declaration of "this is happening". If another driver can act to thwart your action in "milliseconds", you didn't have the margin to do it in the first place.
