I'm absolutely down for vehicle registration fees to relate to miles driven and weight classifications, and major highways being funded by extra tolling.

The streets in my neighborhood cost way less per mile for maintenance than giant highways with massive bridges and interchanges. It makes sense they'd cost more to use.

Showing the real cost of these things to consumers might make them change their minds about riding the train. These days a lot of people don't even think about the cost of driving their car across town, but gosh that metro day pass is $5? How expensive!
