Ray, a drop of golden dumb

Even as a conservative, I am for green technology incentives. I also understand that our transportation/highway infrastructure is outdated (Eisenhower outdated). However, I don't think that replacing the gas tax with a miles-traveled tax, as proposed by Transportation Secretary Ray LaHood (former R representative from Illinois), is the solution. In fact, I think that it is down-right unfair - especially for western states such as Texas.

A. It is not uncommon to have to drive 20 miles or more to a grocery store, gas station, pharmacy, sometimes even a neighbor, etc.
B. We don't have the option to hop on the Subway to work/anywhere local. And building mass transit in Texas is expensive due to how spread out everything is, plus the general high cost associated with building on pre-existing infrastructure.
C. How do they plan to install "global satellite positioning technology, a transponder, a clock and other equipment to record how many miles a vehicle was driven, whether it was driven on highways or secondary roads, and even whether it was driven during peak traffic periods or off-peak hours" into every vehicle? How much would it cost?

Now, the one good I can see coming from this is encouraging more people to live closer to their work (to minimize their commuted miles). And I am all for the reduction of exurbs. However, I feel like the gas tax/high gas prices also helped with relocation. This new suggestion seems to hurt the incentive to buy hybrid/more energy efficient cars.
