I don't drive, in theory I can drive but I sold my car because I never used it. My partner has a driving licence but has never owned a car and probably not been behind the wheel of a car since. My best friends are a married couple and neither drives. I literally know one single person in London who owns a car (on the flipside most of all of my non-London friends have cars).
I have over 30 cafes and restaurants, 6 supermarkets, cinemas, 2 leisure centres/gyms, 3 GP surgeries, 2 major hospitals, tons of chemists and other shops, a train and a tube station, and about a million bus stops, all within a 10 minute walk of my flat. There's literally nothing I could need or want that isn't easily accessible, unless I suddenly wake up with a passion for glacier climbing.
It's weird that people assume all non-drivers constantly get others to "ferry them around." I can't remember the last time I was inside a car. Apart from taxis when abroad, I've probably only been inside a car a handful of times in the past ten years.
Not driving has never affected my employment options since I have no desire to become a travelling salesperson or a long distance lorry driver.
Obviously people who live rurally, or even in suburban areas that are less well served by public transport do need to drive, and I'd never judge someone for that because clearly there are plenty of places in the UK where a car is an absolute need. If non-drivers can accept that some people's lifestyles really do necessitate cars, why can drivers not accept that other lifestyles really don't?
