I think once you get a car (we've got one but I don't drive) you do tend to base your social life around it more - because, yes, it is convenient, warm, and nice to take your world with on the way. I notice how that (tendency to think 'can I drive to x, y or z?') happened to us after we got a car in our early 30s, so I try to resist ... and as a non-driver I've always bussed it, so never really got out the habit like my husband did.

Most young people I know in London are non-drivers and majority of the audience in places like the Ritzy seem to be the under 30s, so I don't think that is much of an issue.
