Road maintenance has to be funded, and will be done in a way that avoids change and angering people who actually care (when change becomes necessary) while being at least a hypothetically good faith effort at fairness. So you shouldn't expect to get tolls (people who drive a lot will care more, plus wealthy suburbanites are more likely to fight this) or weight-based registration (no one drives more than truckers...)

So "hey, those guys stopped paying their share" can be passed,and that's what happens.
