I have that problem, but not with video games. I'm really bad when it comes to driving.
I get pissed off at other drivers very easily and use my horn often. If a driver does something to make me mad I will honk, tailgate them, flip them off, or any combination of those. If people are tailgating me when I'm already going a decent speed I will purposely slow down and match speed with other cars to keep them behind me. I've even yelled at certain people.
It just makes me mad when I drive well and other people act like idiots behind the wheel.
