Great! So now we're going to subsidize the interstate trucking industry even more. Oh, yes. They'll be paid by tolls. But did you catch the fact that a tax credit for those tolls would be provided. That means the rest of us taxpayers will pick up the tab.
And if providing bigger and longer trucks saves so much money, why don't we go even farther and subsidize even longer ones. Light a decent rail system for the country.
