They do that to bikers here in florida.

I keep a couple of lug nuts RTV'd to my handle bars just in case I get someone trying to push my bike down the road for me.

All I have to do is push one off with my thumb, it falls hitting the pavement(slowing greatly), bounces back up and Voila I got a lot more room.

I'd rather not do that, but vehicular assault is not something I take kindly to.
