That's why I'm against anyone who makes such suggestions along the lines of "but its only $10 per year". Maybe it'll start off like that but once all then information has been collected (yeah these bunch of dudes have bikes, make sure to get 'em), the prices will inevitably increase (hey we goota cover our admin expenses). No one will suggest to take money from lower greenhouse emotions from bikes and plough that money into bike infrastructure.

Sometimes I think any one who suggests such bike fees to be government spies.
