I've made it to my late 30s only owning a car for maybe 2 or 3 of those years. I've never felt the desire, my mom always commented it was odd back when I was a teenager... But I digress, it is very possible and it's easier than ever. I grew up on the rural west coast, moved inland to an agricultural area. Never living in a proper city by most metrics. Certainly I've missed some opportunities along the way, c'est la vie, but it is easier than ever and I'm meeting more and more people like me as time goes on. I also don't have a photo ID as a general rule, but that's a whole different can of worms and in some cases much more limiting than living car free. Most people seem to create their own hurdles or embiggen real ones that they do face, certainly I do in my own ways so don't take that as a judgement just an observation. Choosing to go carless is not half the hurdle many people perceive it to be.
