When and why are cigarette lighters and ash trays no longer in vehicles?

When I was living in europe, AC was considered a luxury feature

Anyways, over the years, only 2 of our cars had AC, but all the others still had cigarette lighters and ashtrays, even the truly bare bones cars without power steering or power brakes

Earlier, I had mentioned that I used to smoke once upon a time

But I never smoked in any of our cars . . . I wonder if that’s common, as far as smokers and/or ex-smokers goes

thus, none of our cars ever had a problem with that “yellowed” headliner

my grandmother was a lifelong smoker, and she most definitely smoked in all of her various cars. And they all had that “yellowed” headliner
