> Public transit like buses and lightrail are significantly more efficient per person than personal vehicles. I would be interested to see a study on that. I see many buses driving around with zero or one passengers on them. If a bus is full, the efficiency would be off the charts. But for a city like Portland, that only happens during commute times. The rest of the time, the buses are driving around empty.
