I only learned in the last year - because I had a windfall that was unexpected, and I had previously thrown lot of money at it and kept failing. I was obviously more confident and better now I'm older. People are saying "Oh I bet you wish you'd done it sooner" which I correct to "I wish I'd been able to do it sooner" I tried, it didn't happen and it was becoming a waste of money so I stopped trying for a good 10 years.
Before that I was subject to such comments, people amazed that I managed my life without a car and still did stuff! Always had a ft job, brought up a child, went out, got shopping, went on holiday. My personality, or my life, hasn't suddenly changed overnight. I still do pretty much the same stuff, it's more convenient sure, but I never had the urge to go camping at 3am or to live in the arse end of nowhere (more than I already do, or can afford to) and still don't.
I don't understand why people get so bent out of shape over it and insist it's an 'essential life skill' a useful one sure, but it's not essential because I managed perfectly fine without one. In fact I'd say I'm probably better at planning and more resourceful than someone that's reliant on their car "Can't do x,y,z because car's in the garage/off the road" that wouldn't occur to me, my car in the garage just means my keys feel lighter and I walk or get on the bus! Yet on here you're told you're lazy, infantile, can't be bothered etc etc for not driving when it takes more effort and thought to get around without a car.
It's certainly useful but it's not essential because I've arranged my life around not having one, because although I didn't have a driving licence, funnily enough I was able to do that anyway - even without a driving licence.
The town I work in is renowned for parking being awful, there was recently an event that would mean it'd be nigh on impossible, I got the bus because that just made sense to me, others were gobsmacked that I did it, although they spent ages trying to find somewhere to park and walked a couple of miles to work because there was no parking nearer - which seems a much harder way to do it!
I think for some they know how reliant they are on their car and know they'd struggle with not having one and somehow feel like someone who can is making them feel inferior and so feel the need to make the non drivers feel inferior.
Literally the only person inconvenienced by me not driving, or who now benefits from the convenience of driving is me, I didn't rely on anyone else before for lifts, I don't now, it's just my mode of transport has changed.
