What part of turn and brake signals don't you understand?...

But a friend of mine pointed out that if the other guy gets sue happy later on and happens to remember you license plate, they could call the cops weeks later and tell them any story they want.

yeah, that happened to a guy I used to work with. the guy came back a year later claiming permanent neck injury, suing for all the money in the world, the whole nine yards. There was no good way out of it so he had to declare bankruptcy.
