The issues that you give people the hand and they pick the arm.
I mean, a little bumping is okay, SC racing has this sort of things.
What you can't do is simply ram against the cars that are passing you for the lulz, and because your truck is heavier.
You don't see people ramming each other in ROAR nats, p.ex
Or you don't see people ramming each other AT ALL in buggy racing, at any level of competition.
When it's not high competition, SC racing is a basherfest, where the heavier and sturdier truck wins (Destruction Derby anyone?).
In races where AE dominate there's not that much bashing, basically because us, AE drivers, know that the SC10 4x4 is very light, and with a small bump it rolls over the track.
