It seems that driver courtesy is general is getting worse as the years go by. Assuming you live through an incident, the camera would be a good documentary of what really happened.

Its a shame that accidents involving cyclists aren't treated the same as pedestrian accidents...vehicular manslaughter would definitely opens some people's eyes. An oops in a car usually involve an insurance call and an exchange of numbers. An oops with a cyclist involves a trip to the hospital or morgue.
