When I got married and had a child, I went from car free to one car. Still a low car lifestyle (commute and grocery shop by bike, prioritized a walkable location during our house search, etc) but my car usage definitely increased.

Still, it increased much less than it otherwise would have because we love getting around without a car and because driving is not a status signal to our peers. I might be wrong, having not lived through previous generations, but I think actively preferring to not drive is relatively common now, and it seems like there used to be some stigma attached to not owning a car that is now utterly absent.
