I disagree; many cyclists bike to save time, i.e. because car parking is inconvenient, or because the time it would take them to earn the money to pay for car ownership is much greater than the time car ownership would save them. Health oriented cyclists may overlap their commuting time with their exercise time, but often find that their bike commute is substantially longer than they need for their exercise goals. Schedules shift, and people end up running late. When the utility cyclist is on the bicycle, she may value her time as much as anyone else on the road.
