Some accidents are unavoidable. Instead of worrying about what you can’t control, I advise driving the biggest gas- or diesel-guzzling truck you can buy. That way, when you do happen to slam into a car with a 0bama bumper sticker, you can just keep going and later wipe that Prius off your front bumper like any other disgusting insect splat.
Living in TRUE BLUE Puget Sound, I was driving down 512 a couple weeks ago, headed to Tacoma in my 1965 Dodge Dart. Came across a 60 something gentleman driving a Prius with vanity plates that read ‘LowC02’ and an Obama sticker. Just had to shake my head and laugh. NO WAY was I gonna take the chance of hurting my Dart! LOL! Although, it’s probably got more steel just in the hood than the ENTIRE Prius!
