I'm 42 and don't have a drivers license. My dad tried to nudge me into learning to drive, but I had no interest - it seemed to me to be a waste of time. Of course, I lived in Norway, and public transport was good. I now live in London, and transport is still good.
I've never really felt limited, though certainly there are places that would be expensive for me to get to thanks to the need of long taxi rides etc., but there are also far more places to go than I can get to see in a lifetime that are still easily accessible with public transport.
I something think maybe I should get a license so I could at least rent a car for certain places, but I've just never felt it's been important enough to get around to it.
Had I lived in the US, the situation certainly would be different - I have spent quite a lot of time in the Bay Area without a car pre-Uber/Lyft, and it certainly is possible but awkward even when you're there as a single person, and many other places I've visited in the US has been much worse.
But the thing is, I can totally see a lot of people there too adapting their life after what works with these services. A car is practical in some respects, but you have to deal with service and insurance and parking, and without it you can often spend a portion of that money living in a location where there's less need for a car to begin with, and a portion of it on taxis/Uber/Lyft. And then I can sit back and read or nap.
Of course it depends on the type of jobs you want etc.
