Robert Salladay on the California DMV’s plans to replace the gas tax with a mileage tax based on miles driven:

Gov. Arnold Schwarzenegger on Monday appointed a new Department of Motor Vehicles director who has advocated taxing motorists for every mile they drive ? by placing tracking devices in their cars.
The idea would mean a significant overhaul of how California collects taxes to maintain its often-crumbling roads. Under the plan, the state gas tax ? now 18 cents a gallon ? would be replaced with a tax on every mile traveled by each car and truck.
