from my dad's story that there was huge pushback back in the 80's. And even through the 90's and early 2000's you'd see big "click it or ticket" campaigns because people were still not wearing them. By now you'd think that folks have seen enough stories like this to realize the danger and just wear their seatbelts.

It all speaks back to the mask wearing issue - with seatbelts there is a VERY clear and direct cause/effect right there to see and you still had decades of pushback and defiance. So for certain people, they'll never get it with masks - because the cause/effect there isn't as instant, given the time to get sick, show symptoms, etc.
