The idea that drivers are driving purely on an ideological basis is simply fallacious.

Transit works great for direct trips, where one is going is within walking distance, regular schedules, and little to no baggage.

The 9 to 5 office worker who lives and works near a train stop on a straight commute, is ideal. Not so the plumber with 5 heavy tool boxes.

One solution is a tiny commuter car share - like a bike share. Take transit to point X. From there on, get in the commuter car. This is something only slightly larger than a motorcycle, with a small trunk, suitable for 75% of rides.

The benefit, these cars are tiny so 2-3 will fit in the space of 1 large car. And mass transit can be used for the suitable parts of the trip.

However, this doesn't require tolls to implement.
