Someday we will get speeding tickets for being flashed in two different places based on the time it took us to travel the distance.
Worst part is, in a stretch of road with for instance 15 camera's . they won't take the average speed between camera 0 and 14, they'll fine you for the most expensive one.
So:
if you average 100 Km/h from 0-14,
and average 115 Km/h from 0-5,
and average 117 Km/h from 8-9.
You get a fine for the 117 km/h
