It may be Econ 101 but a lot of people (aka voters) tend not to like fee schemes that make it blindingly obvious that the wealthy are effectively allowed to use public infrastructure in ways that they are not.
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.
That's a very Ameri-centric view. In most European countries people of all classes live near and regularly take public transit.
