CharlieS posted:A city like New York would never be able to switch to driver-less cars instead of buses and trains, the density of folks per square foot would be too low. If you took a full subway car, how many feet of automobiles would it take to hold all those folks at one person per car?
Agreed, I think that would be true in any densely populated city, the whole idea of driverless cars using subway tunnels and transit right of way makes no sense. I am not even sure they would help the situation in places like Atlanta and Houston and Phoenix that have such problems with congestion, driverless cars might be able to operate more efficiently but roads still have their limits. Sadly more than a few see mass transit as a 'loss of freedom' or the like, then complain and moan having to drive in traffic, they complain about the cost of mass transit but ignore the cost of roads and bridges, because to a large extent it is hidden from them.
