Usually just say "What the fuck, retard" to myself.
Occasionally if someone cuts me off or passes me then goes slower than me, I will speed past them and flip them off.
I HATE when you're going 40 mph down a main street, with nobody behind you, then some jackass just HAS to turn from a parking lot into your lane slow as fuck n make you hit your breaks. This pisses me off so bad. Like, the options should be either floor it to keep pace or wait until I pass you. Just thinking about it irks me.
It takes major willpower to not just smash into their back end. Would be their fault as I had the right of way.
