Although I also enjoyed running down to the corner without my seatbelt... or maybe even taking a short ride on a motorcycle without a helmet, it was always those close calls and driving without seat belt tickets that kept me on the straight and narrow...
I also learned the importance of restraints, helmets and fire suits at the British School of Motor Racing... you can actually control the vehicle with more confidence while using restraints - on or off the track.
here's a fun video.... glad I'm not a crash test dummy driving around in an egg..
