Yeah, another tax. That should fix all the problems.
Big Brother could care less about the tax. They already get money through the gas tax. It's mainly a way for them to track our every move and then punish certain driving and other behaviors with increased taxes and fines, or even criminal prosecution.
The government will use it to monitor our commute habits, driving speed, parking locations, meetings we attend, who our friends our, what bar we attend, etc, etc.
It is one of the most significant threats to freedom ever proposed in this country and must be fought tooth and nail.
