Most cyclists also drive, also own homes and businesses, and so also pay taxes for transportation infrastructure. The complaint that cyclists don't pay for the roads just isn't true. Cycling infrastructure, as good as it is, is still woefully thin. I don't think it would hurt cyclists to have to pay a registration fee or license fee to help pay for more bike lanes/bike paths/bike boulevards etc. And sure, if cyclists ignore the rules of the road, they also should be cited and fined. It's only fair.
