I just spent a year and a half without a car, and it was a nightmare some weeks. It basically means no spontaneous trips unless you happen to have an extra half an hour to get there, on average. Oh, and the choice between spending several hours a week grocery shopping (mostly in walking to and from the store) or paying 15% extra to have most stuff delivered isn't fun. I think if you put an hourly price on all the inconvenience, a car comes off as the less expensive option.
