In France they have a system that sort of works like this, most/many highways are toll based. There are toll booths at regular intervals(every 100 miles or so). If your time between toll booths is below a certain time, they know you were speeding at some point. To get around this, my always speeding grandpere would just have us stop for gas, un cafe, etc right before each toll booth.

That sort of defeats the point of speeding. Why endanger your lives and the lives of the others if you even don't get faster to your destination as you make additional stops to "defeat" anti-speeding systems?
I don't think his speeding was a logical, reasoned thing

You are supposing he stops for gas when his tank is full?
I'm supposing he stops for gas when his tank is still more than half-full to top it up, so that he stops exactly enough times to avoid being fined for speeding.
The one I've seen were not installed on the toll booths themselves (those are only there when entering or exiting the freeway) but on separate kind of portals above the road.
A camera records the traffic, a computer extract the plates. Then later you have the same setup, and they can then calculate your average speed between the two. The French name is "radar tronçon".
