At first this sounds like a bad idea, but it's not, here's why. - David Lynch

1. Cars can still be taxed based on mpg of the car. - David Lynch

2. There is no way to tax electric cars (energy consumption) specifically. - David Lynch

3. We need gps in cars, anyway, for a whole host of reasons. Real time tracking is a software/policy decision, not a requirement for taxing. - David Lynch

If you do not want gps in your car, you should be allowed to pay on another (more expensive) plan, such as an up front cost, or per having your gas mileage checked. - David Lynch

4. There are too many converging reasons why gps billing, or data collection is useful. Really this is all about embracing technology. Tolls, traffic, parking tickets, finding parking spaces, gps could eliminate all of this. - David Lynch

5. Big brother concerns don't outweigh the utility(and are sort of a catch all exaggeration), and protections ultimately come back to our legal system of justice. - David Lynch

Lets just assume gps should be required for safety; ie, it will usually beep when you go off the road. Now the question becomes, when to send data to a third party. It's a software question.. a policy question. Yes it opens the door to misuse, and unproductive taxing, but taking advantage of benefits, still leaves us with the same questions; how the software and policy should protect our rights. - David Lynch

that gives me another idea, gps + cruise control, could equal slightly better gas mileage on the open road. :P - David Lynch
