Nobody should dare to touch my car with his.
Anyways, whenever I park in a creative way, which might annoy people or next to someone who seems to be a bad driver and likely to damge my car (hitting his fucking door against mine) I take pictures of the licence plates, so I know who I can contact in case of a damage to my car.
I can understand your rage, although you could have reacted a bit less violent.
If someone smashed my car, I d probably hunt him down and kill him. Seriously.
I d prepare a kill room, complete with plastic wrapping and pictures of the car he hurt and then I d collect a blood sample and push a knife into his scrupulous black heart.
Out of fear from vandalism by wannabe traffic teachers or retired janitors, I usually park carefully.
Out of fear from stupid, thoughtless morons or women drivers, I usually park far away from others, even if I have to walk.
I am really sensitive about my car and everyday I see other people who got on the road for no other reason than to damage my car or at least annoy me.
