> In practice this would probably look like a $5-50 monthly bill I divided my state's total transportation expenditures(including fed dollars)[1] by estimated miles driven in 2016[0] and I got 31.5 cents per mile[2]. Is that about the order of magnitude you were thinking? If you drove 5000mi/year that would be about $130/month. In practice the tax would probably be more successful if setup as a refund, like income taxes. So gas would have a huge tax and you'd get a monthly refund based on your actual miles driven. > If we set aside the dystopian concern about tracking, If you carry a cell phone you're already tracked by at least three parties: google/apple, your mobile provider, the nsa. I think we'd be better off discussing as a society how law enforcement should use this information and passing strong privacy laws to regulate its use than avoiding more efficient taxation.
