What I did - Was thankful I bought some rock sliders:
Parked to offload some gear, and some lady in a BRAND NEW mercedes parks right next to me. Of course she's on the phone, with her coffee, and she doesn't even look before swinging her driver's door out full bore. SMACK against my right rock slider, leaving a softball sized dent in her door.
She begins flipping her shit as I walk out (barely a mark on the powder coating, haha), as she's essentially rage crying. She's so upset, that she's trying to get my insurance information, then she gets it in her head (a gamble perhaps) to claim the rock sliders are somehow illegal. She calls the cop while I and witnesses are just dumbfounded.
Cops show up 5 minutes later, take one look at the situation, compliment me on the 4Runner, and then drive off. She struck me (pardon the pun) as the kind of person who had I not had the rock sliders, and had bashed my door, would have driven off without leaving any information.
Thank you Demello Offroad!
