@Candied My first point would be fudged by saying that it wouldn't be a major problem if I just did the drive down to Devon - it's hardly a frequent thing.
London really has got public transport cracked - 24/7 buses, night tube, and always reliable unless something happens like signal failure or a jumper. I feel hard done by if I have to wait 5 mins for a tube to arrive. Living in outer zone 2, I never feel the need to venture beyond Zone 3, unless I'm leaving London to visit family or for work reasons.
That said, I'm leaving London due to the house prices - I'll never be able to save up a deposit for a flat this side of retirement, despite being on a good income. London is great, but you do pay through the nose for it. I've chosen my next abode for proximity to the services I need (park for DDog, city centre, mainline train station) so I can't see any need to have a car there either (shame I'll still be lumbered with the company car).
@IndieTara it's ranty and rudely put, but he does have a point about having better things to spend money on than a car. No one ever looked back on their deathbed and wished they'd spent more time driving; many people look back on life and wish they'd travelled to more countries.
If something as small as not driving when you live in a city puts someone off, I can't help but feel they're going to find something equally disagreeable in every man out there.
