The article states we already pay per mile, via gas taxes. This means drivers pay different rate per mile, depending on how efficient their car burns gas, which is presumably itself a function of engine as well as chosen tires and weight of the vehicle, ie, how the car impacts the road. The article then says legislation is needed to change us from paying per mile, to paying ... per mile, but in a way which is a hell of a lot more intrusive to the driver: cell phone tracking. I remain unconvinced this is not about tracking and is about paying for the roads. What's wrong with just increasing the gas taxes appropriately?
