I’m not sure fuel could ever be taxed high enough to repair the roads/infrastructure. We’re talking hundreds of billions if not trillions of dollars in work needed. The US federal government is so far in debt that in the next decade the largest single expense will be paying interest on said debts.

The problem with fuel taxes is that they are effectively a consumption tax in the US. Sure you can do it but the general population is living paycheck to paycheck while the ultra wealthy can pull up plenty of money for about a trillion dollars in AI data centers.
