I've had one for 20 years. I can count on the fingers of one had the number of times I've really needed it. Contrarily, at those time I REALLY needed it, so I'm glad I have it. I used ever year to listen to ATC at Oshkosh.
Exactly. In almost 40 years of driving I've only needed a seatbelt once. That one time, though, it came in pretty handy. Much happier dealing with bruises and scrapes from the belt instead of picking glass out of my forehead (or much, much worse)
