> the government is paying $0.84/mile for people to ride BART

If BART disappeared tomorrow, how much would the government have to pay to build all the additional roads and parking to support that incremental traffic?

And how much for healthcare for all the incremental pollution and collisions?

> several cents per vehicle mile

It's close to a dollar per mile when you include all the externalized costs.

Incremental property damage, injuries and fatalities, incremental chronic illness from pollution, parking land subsidy, fair market value of incremental land use and rights of way, lost tax revenue from that incremental land use, etc.

Caltrain rides allow riders to be productive during the ride and generate income taxes in a way that cars do not.

In general, this is why semi-private or private transport works so much better. If the end user is getting a bunch more value out of working on the train, they will pay more for the train than the road (if they have to pay the full price of the road vs train each time they use each).

		“Works so much better” Can you back up that claim? Which world cities with admirable transport systems have this model?
