Review this thread about a biker that gave a person passing him the finger for passing too close... Then the driver tried to run the biker off the road, and eventually hopped out of the vehicle and knocked the bicyclist off of the bike.

I just ignore the bad drivers as much as possible.

I have thought it would be good to photograph the ones that pass cars coming towards me... that is hair raising.
