How was it in the 60s-80s?

I get it, It's the "Thought" of freedom as the government didn't have laws that required their use. I wouldn't think to drive without being buckled now.
Hey , How about the 5 mph bumpers of the 70's that the government "required".Crap cars now have bumpers that are foam covered with plastic that at 5 mph cost no less that $3000 to fix.
