That kind of stuff happens all over. I have punks all the time pullup on my bumper when I'm driving the wifes crew cab. I promtly put the away with my 6.0 small block. Some one alway thinks they are better and faster than you. I personally just don't give a crap.
It all starts with the Parents! Nowadays most kids do not have respect for the law or for themselves and just do whatever they want, The parents give them the toys to get them out of there hair1 Then when they get in trouble, you hear- "My son/daughter would never do that!" What they need is an ass woopin a few groundings, a trip to boot camp then maybe they will learn what respect is!
