I like my car too much to risk it. My preferred method is to just take my foot off the gas and coast, to a stop if need be, till they go around me. Pisses em’ off just as much but doesn’t put my bumper at risk. Plus it’s not an incitement if you wind up needing to talk to the cops, you were just slowing down to let them around you.
Good advice here, but if in slowing and not jamming on the brakes you could be seen to be deferring to them. This is less provocative. What I do in Canada- and yes the bloomin' yahoos are aplenty, is this. I put on my right turn signals and cram over to the right, if I am able. I am thus signalling to the yahoo, I am deferring to his ruddy idiocy. I do not give a rap about such a person, cos' one day he is going to face the wrong hombre (laughs).
The cost and the bureaucracy in Canada( which is an excellent country and civilized) of a fender bender is mind boggling. I would rather pull in for a coffee at Hortons all in one piece.
Excuse the ramble.
