I don't care how tough anyone is on the internet. Hit one of my nice cars, and you are going nowhere. If I have to pull my car into the street in front of you, and stand in the way behind you, so be it. Worse thing that can happen is police show up and tell me to move it, and by then, objective accomplished. Lose your cool and initiate violence before then because you can't flee an accident you caused, it will just make matters worse for you. Not only do you unnecessarily endanger yourself, you also place the favor of the courts and law on my side. "Officer I tried to approach to see if he was alright and get insurance information and I saw him reaching for a gun..." or "he tried to run me over." Who's going to tell your side of the story?
Man up and take care of shit you cause, and we have no problem. Accidents happen, it's not a big deal, just take care of it. Your plasma TV can just wait until you pay to have the car fixed that you wrecked.
I'm not a mean person, certainly not even the kind that fakes wearing a neck brace to get money. I just want my car fixed; $100 or $5,000, it's not my mistake to pay for.
