Compared to private cars, public transit has the potential to prevent traffic congestion, save fuel, and save time for the average rider. However, public transit ''done wrong'' could actually use ''more'' fuel per rider - especially in places where buses run mostly empty most of the time.{{qn}} Low-density suburbs are particularly hard to service in an energy-efficient way, for thi...")
