    It's just a decoy. They really use drones.

    There are lines on the highway the aircraft can see form the air, they time the distance going between those lines and have a chart to figure out your speed, they then radio to patrol units on the ground to stop speeding vehicles.

    That's something called "vascar".

    The way it works is an officer in the air in a helicopter watches the highway and times peoples' travel between white lines painted within the lanes. Vehicles with less than certain times are radioed to officers in cars on the ground who then stops the offending vehicle and issues a citation.

    I'm not sure how often this method of speed enforcement is actually used, but these tickets can be beaten in court fairly easily if you take the time to cross examine the officer. You can blow some big holes in their case, especially if both officers aren't present.

    It means nothing. There was a story on some news show about it a few years ago that most states have no money for this anymore.

    If you look at the road, you may see some large lines painted from one side of the road to the other. They may even look like large blocks of paint.

    What they do is observe a vehicle and time how long it takes for them to travel from one line to another. With some simple math, law enforcement in the air can tell how fast that vehicle is travelling.

    Then they will relay to ground units to stop the vehicle if it is speeding.

    Very interesting to listen to actually.

    MO Highway Patrol used to do it quite a bit... Don't know how often they do it anymore. Since I'm not home much these days.
