Why? It ties taxation to usage and is uniform between dino-burners and electrics. Every street-legal vehicle already has one, so the question is really how to get an authenticated reading once per year/period.

I assume you are talking about annual mileage charge (based on odometer readings) and it was read as constant GPS tracking to charge continuously based on mileage.

Annual odometer reporting is totally fine, of course. I read "logger" as "continuous data logger." That's never going to be acceptable.

I assume you already carry a continuous data logger in your pocket. At least it's voluntary. ;)

I don't know what the most practical solution is while still being respectful of people's privacy. It could be a combination of GPS and an odometer or just one of these or something else. It doesn't have to leave the car and only the total number each year is important. You just need to somehow make sure the results weren't tampered with.

Keeping people from messing with the odometers is really important already. I doubt the tax cheating will be the motivators.

If this is a solved problem all the better, then the tech is ready. Now only the people problem, which is the biggest hurdle, is left. If you think raising taxes for the people that use the shared resource is a good solution of course. I think letting the users that use a shared resource pay for it is an acceptable solution, but not everyone thinks that.
