  • There’s almost no reason for having two of them other than to measure speed, otherwise you’d only use one. But it’s not for enforcement, it’s to see how fast most drivers actually drive the road. This can be used for things like adjusting the speed limit, or testing to see if measures need to be taken to enforce it more strictly, etc. I know there is a hill in my hometown that residents used to always complain about speeding. They used exactly this setup to track the speed of drivers. They found that there was no excess in speeding, the steep hill required more gas to maintain speed, and people generally associate louder engine noise with higher speed.
