A NEW BILL HAS BEEN INTRODUCED THAT PROPOSES A MILEAGE TAX ON CALIFORNIA DRIVERS.   THE LEGISLATION SEEKS TO TAX 5-CENTS PER MILE DRIVEN INSTEAD OF TAXING BY THE GALLON. WITH MORE FUEL-EFFICIENT VEHICLES ON THE ROAD, THE STATE HAS LOST REVENUE FOR THE FEDERAL HIGHWAY FUND.          CAL-TRANS WILL LOOK INTO WAYS TO TRACK MILEAGE INCLUDING INSTALLING DEVICES IN CARS.     IF THE BILL PASSES, A PILOT PROGRAM WILL BE PUT INTO PLACE IN 2017.
