> Freeways can get 2000 cars per hour per lane

I'm missing something, in a single lane at 60mph you would be able to get ((60 * 1608)/5) (assuming car is 5m long) = 19296.

If we assume that there is 5m of seperation between every car (possible when all cars are automatically driven and communicate with each other) that's still 10k cars an hour.

4 lane highway, 40k an hour, assuming occupancy at 1.6 that's 64000 an hour.

Human driven no way, we are too unpredictable and react far too slowly to safely drive in that way but computers probably could.

Well you just made a pretty unfair comparison since you added up to 64000 for all four lanes vs 100000 people /per track/ on a 4-track railway. But I think your assumptions are all pretty optimistic. You wouldn't be able to run cars that close together on a multilane roadway because cars would need to move between lanes to enter and exit which would cause pipeline shocks if there was that little room.

Anyway the main difference between my claims and yours is that yours are speculation, while mine are based on history. We've seen five million people disembark at actual railroad stations. It's happened. We don't have to speculate.
