Another thing to consider is the illusion of closure. For your average commuter, they wouldn't be happy with tolls (no matter the type) but they'd tolerate them. Upscale folks might actually like them because their money grants them the privilege of using the road with light traffic.
But to the lower middle-class and the poor, a toll is a slap in the face. They see the toll booth, and it sends a message: "You don't have the right to travel."
I'd rather have a more socialized world where we take down barriers to entry, allowing people the right to move. I'd also support removing fares from mass-transit, using sales taxes to pay for it instead. Ridership would go up, for sure. I know I'd be much more inclined to ride a bus for a few blocks. But fareless transit is an unpopular idea with quite a few people.
So, although I can see logic in your idea Wasden, I could not support it on principle. Tolls close society, and divide us into classes: Those who drive the toll roads and those who drive the prole roads.
Tolls make travel harder. Government's job is to make travel easier. That's why we pay taxes!
