The REALLY NEAT thing about charging people by the mile is that government can base the rates on where people drive, when people drive, what people drive, and even their reported income level, should they choose to.
Also, instead of widening or upgrading highways, they can simply raise the prices of using them, cutting down or eliminating the congestion! Then with the huge revenue they’d be generating by raising the prices, they can send that money to more important things, like Obamacare, New York’s mass transportation systems, Section 8, SNAP, and other higher priority uses which affords them many more votes.
So it’s hard to see a downside to tracking and tolling people as they drive!
The guberment would rather spend millions on fancy rest stops that fix the roads. Some of the rest stops here in Missouri look like small cities.
