I would be surprised if even the most used bike paths around here carry 1% as many commuters in a given day as the road does right next to it with cars.
Cyclists pay more than their share. Gas and license fees don't pay the full cost of the road, so other taxpayers, including cyclists actually subsidize drivers through general taxes.
