There’s a huge difference between losing your temper when controlling a digital go-kart versus a real-life one-ton vehicle.

It’s a good first step that you recognize this is a problem, but it needs to be followed up with actions you can take when it occurs. In the case of driving, if your impulse is to follow the driver who pissed you off, you need to get off the road at the very first safe opportunity (a side street, a freeway exit, a parking lot, whatever) to give yourself a chance to cool down and both mentally and physically distance yourself from the situation. It doesn’t matter how much of a jerk the other party is (again, unless they are actively putting people in danger, in which case you should be pulling over to call emergency services); when you’re on the road the only thing you should be concerned with is your own behavior. There is zero justification for escalation; you are not teaching the other person a lesson, you are putting people’s lives at risk over a minor slight.

I used to work in transportation and you wouldn’t believe the horror stories. Please don’t underestimate how quicky and easily road rage situations can turn ugly; it’s never worth it.
