Yup, bad driving usually brings out the hooligan in me too, although I've learned to control my annoyance.
I hate losing my temper at any time and I've had one or two nasty experiences with road rage (including one guy - with no driving license or insurance who got so mad at me because I was obeying 30mph speed limit that he caused an accident!), so I try and ignore my anger.
If someone is on a mission to cause an accident then I don't want to be part of it.
