To be fair, being reliant on a car also limits people in many ways, but those tend to be less visible because they're so accepted as normal.
Running a car costs a lot, even more than my (extortionate) train season ticket. I've never had to pay that. Nor have I had to stress about finding parking or paying for parking. I don't have to worry about car theft or damage. Cars break down just like trains do, but if my train breaks down the train company will haul it out of the way and put another train on, I don't have to deal with getting it fixed or pay for it myself. I know all the local train and bus routes and times, so I don't have to look them up. And (most appealing personally), if I'm travelling, I can read a book or knit or whatever I fancy at the same time, because I'm not the one responsible for paying attention to the road.
I'm not saying this makes me freer than drivers, or makes me a more adventurous or independent person.
I got a taxi to hospital when I was in labour. This is something that many of my friends find horrifying even now. But... why? They got to driven by stressed panicking husbands and partners, were alone for a while in maternity triage while said stressed new dad faffed around acres of car parking looking for a space and got back to the building. I got a fast, professional car journey, sat in the back of a black cab with DH, got straight to the door of the hospital and nobody had to go off and find somewhere to park. So I think that worked out brilliantly, but I know to some of my friends who drive this is an absolute horror story - "and she even had to get a TAXI to HOSPITAL in LABOUR!" It's all perspective.
