Hey, the best thing to do with irrate motorists, is just shake off whatever they throw at you verbally or give you with sign language. I get it quite frequently, and it just doesn't bother me anymore. Motorists these days are always so much in a hurry. Getting behind a bicyclist or having to wait for a bicyclist to pass before they can go, just irritates them to no end. One day I would like to see that people here in the USA eventually respect people on bicycles, the same as the people in Europe respect bicyclists over there. I am not holding my breath though.
