I think cyclists should have insurance, it isn't much ( I paid £100 p/a)
swerve onto the runway at Heathrow and cause a plane to crash into an apartment block seriously maiming and killing a few hundred then I reckon the damages will be over the insured amount. Don't actually try this though....
Less than £10 a month isn't much if your cycling. After all, your saving on petrol and public transport. If it also means that cyclists become more accountable, then that can only be good for everyone. Surely??
