I've conditioned myself to be a lot more zen-like about driving. I don't get mad about people cutting me off, I just laugh it off with amusement now. Sometimes if I am in a rush to get somewhere, I might reluctantly cut someone off, but try to avoid any crazy stunts. Majority of the time I give myself enough of buffer so I don't have to rush. It's not worth risking your life or the stress to road rage 
pretty much. i like driving fast but just on the highway and even then if someone wants to go faster i'm not going to get in a race with them, i'll move over and let them go on by. and i don't care enough about going fast to tailgate someone because people are stupid/insane/both when it comes to that shit.
i'm against passing on the right but i'd rather do that than engage with someone that is either not paying attention or holding a weird grudge about driving. both are equally dangerous mindsets.
when it comes to just regular roads i'll just stick to the speed limit or at most go 5 over. i've gotten one expensive speeding ticket and that was enough to curb me of that practice.
