Thus it’s easy to compute how many miles the vehicle as been driven in a year.

Good point, but 1) how many miles were driven out-of-state (assuming the State is trying to exercise its own tax power)? And 2) there is another tile to this, which is police control of the population.

This isn't totally about revenue. It's about forcing on people the attitudes and reality of life as a slave.

Ah, out of state miles. Didn’t think of that one.
