> I've been caught by surprise before when a conservative driver slammed on their brakes when the light turned yellow even though there was ample time for both of us to coast through the light.

I witnessed an accident where a tiny little compact slammed on his brakes the second a light turned yellow. Unfortunately, he was being followed by a large SUV. The SUV hit him and pushed him into the intersection.[0] The very next day, at the very same intersection, I saw the now dented compact do the very same thing under the very same circumstances. He had learned nothing.

[0]To make matters worse, he left his perfectly drivable car in the middle of the intersection instead of pulling ahead. He got out of his car, made a phone call, and just stood there in the intersection having a conversation (with police or insurance I would assume), endangering himself and others.
