The introduction of a tax on the mileage of a personal car was promised to the Americans by US Transportation Secretary Pete Buttidzic on March 26 in an interview with CNBC.

Discussing sources of revenue that will help fund infrastructure proposals that are expected to cost trillions in the coming months, Buttidzic said the government needs new "sustainable funding streams."

“The idea that part of how we pay for roads is what you pay based on how much you drive,” Buttigiec said.

The transport minister said the mileage tax is a plan that "looks promising" and could ultimately help finance future infrastructure projects.

Rumors are that tax will be different for different cars. Electric cars tax will be at least 5 times lower.
