exactly! it's why we don't feel bad for slapping a child's hand as he reaches up to a hot stove. yeah, you hurt his hand, but it could have been a lot worse.
ticket cyclists when they run red lights. ticket them when they make unsafe lane changes. maybe start requiring registration (license plates) and through that, they have to pay the road taxes just like other vehicles that use the roads, so that when they do a hit and run, we'll at least have some chance of identifying them. at the very least, require a driving test and issue a license, then if you're caught riding without one, that's another fine on top of whatever it is you did that made you get caught in the first place.
pedestrians have been ticketed for jaywalking, so why not bust these idiot bikers too?
