I think this is one reason you get people talking at cross-purposes about living car free.

Leaving aside where their job actually is... (Which, in the case of many cities may well not be in the city in the case of tech-related jobs.)

People tend to bias their activities to what they can do relatively easily. If you don't own a car and don't have a lot of space, you're probably not going to take up some space-intensive hobby or head off on a lot of weekends to hike or canoe. Maybe you'll lean a bit on friends with cars--though that tends to get harder as people get older and busy with their own activities. And maybe you'll rent a car now and then. But mostly you'll fall into activities that don't have a lot of overhead associated with them.
