If they can track you with GPS, they can do a lot more than simply tax the number of miles you drove. They will know where you went, when you went there, how long you stayed, and how fast you drove.
I guess speeding tickets will start showing up in your mailbox, or worse yet the fines will be drafted out of your bank account.
I totally agree! I think I fear the info they will garner more than the supposed gas tax itself. What freedom?
