The idea of charging drivers by the mile isn't a new one. At least 18 states have studied the idea as one of many ways to replace fuel tax, but no state has implemented it widely, said Jaime Rall, a senior policy specialist with the National Conference of State Legislatures.
"It's a very popular idea to think about, but there's no jurisdiction that has that kind of fee on all vehicles. It's still very much experimental," Rall said. "It's one of the options on the table. Many transportation experts think it's one of the better options, but the general public still has very real concerns about privacy and equity."
I didn't mean to sidetrack a serious thread. My concern is that this, like many taxes, would be put in place under the guise of replacing another, but would actually just be a way of adding more taxes. How often to politicians actually "replace" a tax?
