Let's take Cambridge MA's Central Square station as an example. It's walking distance to a lot of jobs, supermarkets, parks, entertainment, etc. It has the Red Line to downtown Boston every ~3min on peak and ~6min off peak. It has multiple busy bus routes radiating out. It's not the best transit in the world, but it's easily a place you can live without a car. We should allow people to build housing without also building parking in places with transit at least this good.
