If I had a choice in a commute time of 20 minutes by motor vehicle or 2 hours by bicycle, the motor vehicle would win hands down every time. I can factor in the cost difference in my personal time lost, in which I could be doing home/vehicle repairs other than paying someone else to do it, plus the added cost of bike maintenance/wear.

I still get amused by posts claiming that one can have (what I consider) a full on year round commute, and be able to only spend 50 dollars or less a year on bicycle maintenance.
