We have a successful red-light and speeding camera program.    So far, despite a lot of whining against it, it's still in effect. We could have a lot more red-light cameras, for instance--and maybe our taxes would go down. I see cars run red lights constantly, and very few intersections seem to have the cameras (more's the pity).

But jurisdictions make a lot of money on sins of motorists (including parking problems).    DC made $80 milion just on parking tickets last year.
