Highway and transit programs have fallen short of funds as motorists in the US are driving less or switching to more fuel-efficient hybrid cars. Road structure is highly dependent on fuel taxes and plan was proposed to increase fuel taxes temporarily, until a better way to finance roadwork is found.
Another idea is that vehicles should be taxes per actual mileage so that hybrid car owners also contribute to highway and transit programs accordingly. This will involve complex GPS equipment that tracks road usage, which is yet to be put on the drawing board. Until then, an increase in fuel taxes is on the agenda.
