Raced a few cars in my life and times, so wearing a seatbelt has become second nature to me for years. Though early on (my teen years, street racing) not wearing a seatbelt saved my life. I flipped a 67' SS, it landed on the front part of the roof, crushed it down into the front seat, steering wheel area. I was thrown into the back seat and suffered not even a scratch. If I had been strapped in, ouch! Cut out street racing from my life, started racing on a track and been in seatbelts ever since.
BTW, Ron Paul said it best on Leno the other night. "I believe in seat belts but I do not want our government involved in the issue" I like that.
