Yeah. I was recently without a car for three weeks (bangernomics finally stopped winning) and decided that I'd learned the wrong lesson about car dependency: despite living in a city with a decent bus service, I really did benefit a lot from having a car and needed to buy a secondhand one as soon as possible, even though I am waiting for my leased EV to arrive in a few months.

You have to be quite central in quite a big city to not need a car. But that does cover quite a lot of people - I would say much of the population of London and the most central bits of Manchester and Birmingham, which is easily 10-20m people.
