My pet peeve used to be people who fling out their doors in parking lots, hitting the cars beside them. Now I just sit there and laugh. My jeep has steel rock sliders along the sides

(or 'steps' as we call them because I bought them when my wife thought the jeep needed "steps" to get into it better. heh heh Wife authorized upgrade...)

extending out about 3 inches from under the rocker panels. With my Jeep lifted a few inches, it creates the perfect door smashing device for these uncaring people.

One old guy got upset because it folded in the outer lip of his door pretty badly while I had no damage other than yet another scratch on the hardened steel rocker protector. Somehow it was all my fault that he carelessly flung his door open like a madman because he was arguing with his wife.

With great power comes Awesome irresponsibility.
