Yes because no one is immune to the laws of physics. Sometimes you have to force people to have common sense. Because if they get badly injured in a survivable crash from not wearing their seat belts it is society that pays the bills.
I only support an exception if the person injured in an accident loses their medical insurance if they were not wearing a seat belt.
I walked away totally unharmed from a 40 MPH crash when a Tacoma ran a red in front on my Miata and I T-boned him. The car was a write off but between the air bag and seat belts I was fine. In the 60s I broke a windshield with my head in a much slower crash as the car did not have seat belts. My head hurt pretty bad and the damage to my forehead took a long time to heal.
I have been there and fortunately lived through it.
