The problem I run into is time. And sometimes location. My previous job, for instance, was far enough out that there was no bus service; I had to drive. My only other option was a 2-hour transit ride and then a half-hour bike ride, partly on gravel roads.
And my friend has a job that’s 15 minutes by car, or 45 minutes away by bus. Even worse, with recent construction messing with the trains, his commute has gone to 2 hours plus.
And this is in a city with a decently robust transit system.
