[quote name='Magehart']Record mileage during smog check/vehicle service/etc whenever any mechanic that isn't you has access to the odometer. Then ship data to DMV to be compiled in a federal database. Wait 6-8 weeks until your bill arrives. Pay bill. Tell the government to

off and never see a mechanic again. This will teach us all to change our own oil and brakes.
If something like this passes then, as a fair majority has stated, more of us will become outlaws. The government doesn't need to keep a record of how much traveling you do. We should just make everyone pay some percentage of their income every paycheck to the local, state and federal government and be done with all this little taxes. Oh wait...[/QUOTE]
It will happen like this:
Every year you must register your vehicle with the DMV, right?
When you pay your tax, I mean "registration fee" to get your new license tabs, the agent will read and record your mileage and you will be taxed on the spot to re-register your vehicle. You don't pay, you don't drive, it's that simple. It won't take any extra monitoring or equipment.
Don't think this will end with the Fed. When States get the whiff of new revenue, they'll be sure to pass similar bills to get their fair share too. We'll all be subjected to threatened bad road conditions until it passes, too. The State will get their cut, and then pass along the Federal Gov's fees to them quarterly.
