I'm a great driver, and I pretty much never get road rage.
I've consciously worked on separate pieces of my driving strategy one by one over the years, and I have a pretty strict set of rules.
-Don't pass people in turns
-Don't change lanes when someone is two lanes over in the same position
-Never drive in a car's blind spot
-Watch as far ahead as possible and start braking when you see distant brakelights.
-If you miss a turn, just chill and correct it later, don't try to pull a move at the last second.
-If someone cuts you off, oh well. They want it more than you.
-Move to the right lanes if people are driving faster than you, only move left to pass.
-SLOW DOWN before turning. Too slow is much better than too fast. You can accelerate on straightaways.
-Spend as little time as possible next to big-ass trucks, better to break speed limit than to drive next to them.
I have a bunch of other rules that I'm probably forgetting. As long as I hold myself to them, even if I'm mad, I'm pretty damn safe.
It also helps to have good control over the car and to have an intuition for when to accelerate and when to slow down to take turns most efficiently.
Some people may be a bit faster than I am, I guess.
