I don't use a seatbelt.
I used to drive a cab, and in Finland the cab driver is supposed to open the door for the customer and carry his/her bags in etc.. so there's a law, that a professional driver (ie. cab driver) doesn't have to wear a seatbelt. They count on the fact that a professional driver knows how to drive (no dead cabbies because of road accidents so far). Of course I can't trust the other drivers, so they might cause the accident, but it's a bad habit.
I always wear a seatbelt when I drive like over 50 miles or so, when I know I don't have to take it off anytime soon.
