California Road Charge proposal would have motorists pay by miles driven instead of per-gallon gas tax

California is considering replacing its gas tax with a mileage tax due to dwindling revenues caused by the rise in electric vehicles. The proposed "California Road Charge" would tax drivers based on the miles they drive, tracked through various technological means. A pilot program set to begin in June will test the feasibility of this system, with participants potentially earning up to $400.
