I support a gasoline tax instead of a CAFE. A CAFE forces automobile manufacturers to develop fuel saving technologies {at added cost to the vehicle} that the market does not want because gas is cheap.
A tax makes gas expensive, while, as you pointed out, providing funs for better roads; and create a demand or cars with fuel saving technology.
IMO, we pay one way or another.
Like the FRAM add says: "you can pay me now or pay me later"
We chose later and have crappy roads.
