Vehicles already measure how many miles they travel, and we already have periodic inspections. Why not charge vehicles in proportion to the odometer delta? This avoids the surveillance concerns, and is far cheaper to implement. It doesn't tell you how much of the traffic is on roads belonging to different entities, but it seems like sampling should be enough to get a fair decision?
