I still think that gas tax should be very high in dense populated areas and very low in sparsely populated areas. The most interesting aspect of funding our roads is the tax structure and it was only a matter of time before governments started to feel the pinch of more economic vehicles and decreased tax revenues from those gas taxes. Some sort of road use fee will probably be initiated at some point based on vehicle type and weight. Maybe our leaders could figure out what roads are generating revenue and put what money they generated back into those roads and roads that do not generate revenue need private dollars or just fall into disrepair. Hopefully someoone will show some math that makes sense.
