Many years ago, there was a court case here in the US over a fine for excessive average speed over a distance. In the end, the case was decided on behalf of the driver, because the police couldn't prove that the car had not been picked up by a helicopter and moved at high speed through the air, and then put back down on the ground near the other end. I think some laws are going to have to be passed here in the US to make it feasible to use average speed systems. Which I think is actually a good thing. IMO, the police, or whatever system is issuing tickets, should have a minimum necessary amount of information they can prove in court, before they can issue those kinds of tickets.
