The people who end up driving despite the tolls, parking elimination, etc. are those who can't afford the rent near the public transit system. Cars are a significant cost for them, but not as much as the rent premium they'd have to pay for a well-connected location.

It's astonishing how much some people are willing to pay for the pleasure of driving free of traffic... We should charge them as much as they are willing to pay...
