The guy was a real dufus to drive aggressively like he was, and the suit looked like he had given him 3 chances before the film even started.
It was the only way the suit could continue w/o the dufus following him and trying to 'argue' or threaten him with his car as a weapon.
Actually, on the average, LA drivers are the best I've ever seen; but you're going to get some people every now and then that should be institutionalized or are retarded. Still, I hope drivers in LA drivers drive better after this, ha ha: that's my a$$ out there on the road with the random dufus!
Even though the dufus was on his feet when the suit left, he had even more brain damage to deal with after the suit left.
