When I had road rage i had this happen to me and I took it too far. Guy was tailing me at 70mph on highway while the other lanes were open. I got so pissed I slammed my brakes on him, he slammed his brakes on and locked them up, skidded into the shoulder and almost slammed into the guardrail. Was I satisfied then? Yes but afterwards i realized the guy could have been killed which is WAY overboard. I was young and immature. So just stick with the above.
