Cars travel with 80% of their capacity unused. Could you image a bus, truck, ferry, airplane or train operating that wastefully? In some countries nearly every car acts as a taxi, picking up paying hitchhikers, on its way to its destination. The fees pay for gas and maintenance. Before they would do likewise, North Americans would want some technology to let the driver and passenger have some assurance of safety and to handle payment without the danger of cash. The reward for the driver could also be access to HOV (High Occupancy Vehicle) lanes.
