I live in a small town, where there are buses, but they run quite infrequently. No other mass transit exists.

So, out of about 20 people, one walks to work quite frequently (living within blocks of work). I ride to work occasionally now in the Summer (used to ride 3-4 times a week) but I have a scooter now - it's easier. One other lady rides to or from work occasionally and will have her husband drive her the other way. Her commute is about 15 miles.

The rest are one car, one occupant commuters. Even, though at least 2 more people live in walking distance and about 1/2 the remaining people live within 5 miles of the office, they all get into a car and drive by themselves to work.
