A gentleman, sir, does not give another gentleman the finger...
If, however, the other gentleman is a wrecker or an idiot, feel free to give him both fingers
If they ever implement stalling or realistic engine damage in LFS, the raised arm can indicate that you're in trouble and are leaving the track...
I dont know about the shaking of fist (thats a bit aggressive) but I would like to wave hand, or lift it up like "sorry mate". Would be great if messages are banned on the server
Well Blackout, we should have options that would suit the situation: wave politely, thumbs up, shake like a psycho or flip like a cabbie
...or open the glovebox and pull out a 9mm...
I have long wanted the ability to raise an arm, which arm is raised could be used to denote which side you want a leader to pass you.
I really couldn't care about giving the finger to another car. I'd rather not distract myself any more than necessary during a "high adrenaline" moment.
