I agree Andy, a majority of the accidents were caused by biker error, ok not error but lack of respect for other road users.
We all know this kind of riding happens even over here and they wonder why they hate cars. It's because their doing twice the speed you are and making a turn checking mirrors and the next thing WHAM!!! (No not Wham the pop group!)
It's a shame as I admire bikers for their brave riding at speed, but its not to be done during congestion or at cross roads etc, as an example.
Hey I used to love Barry Sheen a legend, but you'd never see me on a bike. It's a shame really.
