Vehicle Miles Traveled is not just about road taxes. It is about behavior modification. They will base your tax on the type of car you drive, what time you go to work and your fuel efficiency. See the "Future of Tax Regulations" video especially the first two minutes by a tax expert. BTW, all of these industry folks seem to be excited about this as a BENEFIT to their business. I expect most of them do not work at the 85% of small businesses that employ all people.
