I have always worn a seatbelt when driving a car that had seatbelts since 1973. Never had a problem wearing one, its automatic for me, first thing I do when I get in the car is put on my seatbelt. It has nothing to do with any laws just something I was taught by my parents. I was taught that a seatbelt helps you stay behind the wheel and in control of the car while driving and when necessary avoiding an accident.
For those who think not wearing a seatbelt is better because they escaped death or serious injury during an accident and were not wearing a seatbelt; I can recall accidents were people were killed or seriously injured because they were ejected from the car and then crushed or hit by other vehicles and the accident itself was survivable. Of course there are going to be accidents where it doesnt matter if you had a seatbelt or not, 80 mph headon with a semi is pretty ugly.
The important thing is to drive defensively, pay attention to the road and conditions and watch the other guy. I'm teaching my son and my daughter to drive by telling them to expect the unexpected, dont just watch the car in front of you but 3 or 4 cars ahead. Watch the drivers behind you and beside you. Beaware of your space on the road and leave yourself some space so you can avoid the idiots that change lanes without looking or fly through traffic like they're racing NASCAR. And when the weather is bad you have double your efforts to protect yourself because those idiots are even worse when the roads are bad.
