There is a lot of talk here that wouldn't be out of place on the comments of a Daily Mail article about cycling.
From the Office of National Statistics:
Motorcyclist road casualties, % from the whole of the UK in 2002: 6.5
Car Occupants road casualties, % from the whole of the UK in 2002: 69.7
We're missing the wood for the trees here. Cars kill, maim, and injure, motorbikes kill, maim and injure, and bitching about some Sunday motorcyclists isn't the best way to stop that. I'm far more concerned about the average joe bloggs monday to friday slaughtering people with their 'right' to drive.
