'Grace isn't born to drive, she's born to be driven,' my mother tells her friends loftily when the subject arises of why her thirty-something daughter still needs to be collected from the station. In a funny way, I think this is true. I still don't drive, but for 15 years I've lived in London where not driving makes perfect sense. There's far too much fun to be had in London without worrying about parking spaces, traffic jams, drink-drive limits and getting your beloved Saab scratched by a bored teenager. I have none of this tedium. And, recession-wise, I don't have a car, so I don't worry about the social humiliation of it being taken off me or what the neighbours will whisper if I downgrade.
