Actually a couple of years ago, the gasoline tax took in more tax money for the Federal Govn't than they were spending on infrastructure repairs and replacements. Congress was using a couple hundred billion out of the gas tax for the general fund. The money has been there, but was spent on something else. Like Social Security, it was solvent and had a big reserve, but when they added medicare and medicaid to it, it dried up. Kind of like we have the best Interstate highway system in the world, and they want mass transit high speed trains. Well that is what the airlines were for, but now it is a bottleneck with all the screening going on. Just something else to spend money on. Europeans and the Japanese can use high speed trains since their countries are only as big as a couple of our states. Air travel is still cheaper and faster than high speed rail. Only for short distances of 400-500 miles or less does high speed rail make it worth wile, but you can drive that in about 6-7 hours and have your car when you get there. So, it is still not worth it. High speed rail will probably end up being like Amtrack, a money hole for our tax dollars to throw in.
