Look at what trucks have to file every quarter. IFTA tax. Have to track fuel usage, purchase etc per state and pay a tax if you bought in a cheaper state and drove in a higher taxed state. This is what these idiots will end up with. And of course it’ll cost more. Plus there will be cheaters everywhere.
IFTA isn't a tax. It's a reconciliation of taxes paid, vs. taxes owed. It stands for International Fuel Tax Agreement, and was an agreement between the trucking industry and the states with respect to fuel taxes paid vs. due. Prior to IFTA, companies had to file for permits in, and file tax reports to, each and every state they drove in to pay these same taxes. IFTA isn't the problem. It was a reasonable solution to a problem.
It's quite different for average Joes just driving the family sedan cross-country.
You file that one report to your base jurisdiction and pay any amount due (or get your refund from) that same jurisdiction. Then all the funds sent to your base jurisdiction are sent to/received from the other jurisdictions via a clearing house. You pay no more in taxes than you would have the old way by filing in each and every state in which you drove.
