I know a guy who won a road rage gunfight. He spent a year in jail. I know another guy who lost a roadside gun battle. Became an internet gun guru. Go figure. Meanwhile, keep this simple rule in mind: “tarmac and tires.” If you leave enough space between yourself and the car ahead that you can see both tarmac and the car’s tires you’ll have enough room to escape. Provided there’s room to either side. Failing that, what was it that David Essex said? Rock on! I’m not sure I’d cant my seat backwards before s gets real; who wants to risk losing sight of the bad guy(s)? But opening the door and aiming/shooting through the gap between the door and the car body seems ideal. Especially as you can get back into the car and drive away. Now why did I buy a car without a running board?
