> Getting rid of most of the cars and putting people on trains does wonders for peak throughput. Getting people on trains by forcing them out of cars can't actually do that. If you make it more expensive/inconvenient/impossible to drive, at most the same number of people will take the train. In practice fewer will, because some of them will find jobs somewhere else or do their shopping somewhere else etc. So the comb…
> Getting people on trains by forcing them out of cars can't actually do that. If you make it more expensive/inconvenient/impossible to drive, at most the same number of people will take the train.

If all you're doing is diverting people away from driving, you can't increase overall throughput because there is nowhere you're adding by more than you're subtracting somewhere else.
