Nothing wrong with a nudge, but ramming your paint so hard it sticks isn't. I believe a good bump n run is fair play if don right.

There are few drivers who think getting nudged or bump from behind is enough to reason to retaliate on the track.

I think the best use for moving a guy out of he way is if you are definatly faster and being  blocked and held up. In a case like that when you get by and right way start pulling car lenghs on them it was the right move and there's no way to retaliate. It's another story all together to dive in way to deep only to pile into the car infront of you lap after lap, but we all know that.

I always told Jake "If you're not fast enough to be in the way...Get out of the way" Jake started racing full size cars when he was 12, he's been bumped and runned a zillion times, so muchin fact he's hard to do it too him. We never had too much to say about it as long as the car came back in without allot of damage. The guy in front of you knows how fast you are if you're "letting him know" you are there. It's you're choice to let him go or not, if you choose not to decide, most likely the decision will made for you.

Bump and Run is fine as long as you are not taking the guy out. Sometimes it seems slower cars just want to be in the way and if they can't see you are faster give them a little bump and let them know I'm faster let me by give me some room and if the guy ignores it over and over you don't need me to tell yah what happens next.
