well, there are a lot of people who don’t know about CTC and other organisations. hell, a lot of people don’t think they need insurance for riding a bike (legally you don’t, I know). There are people who ride a bike that’s not worth insuring thus aren’t covered that way either.
I think that if insurance companies offered it as part of car ins then I think more people would be covered. Obviously there are people who ride for the reason they don’t have a car and I don’t know how to target those but for those who have a car and chose to ride to work, they should have an option on their car policy to cover when they aren’t using it.
I’m not saying I think it should be compulsory. it shouldn’t as this would be detrimental to uptake, much like compulsory helmet wearing.
