Re: While were at it....
I'm riding my lightweight road bike, which has a carbon fibre frame, along a city street and crash into you when you cut across in front of me. I'm relatively OK, the bike is still rideable, but your car has a massive scratch across the bonnet. I get back on the bike and cycle off, after telling you what a muppet you've been.
It's like any other hit and run: how is insurance going to help in this case? To complicate matters, I've got no registration number so you can't report my reg number to the police. Do I need a registration number on my bike as well as insurance?
It might *sound* like a sensible idea to require cyclists to have insurance but it's not entirely practical. If that were to happen however I could almost guarantee you that the cost of car insurance overall would go up; more and more cyclists would be claiming on their insurance, and in many cases the car driver is going to be liable. If I was involved in a cycling accident that wasn't my fault and I have insurance, you can be damn sure that I would claim on the insurance for the damage - and you can be damn sure that my insurance would do everything they can to establish that someone else was at fault and recover costs from the other party. If there's one thing that insurance companies are good at it's finding ways to avoid spending money.
