    I never actually understood those. Do they actually have, like… a drone? Is it snapping a photo? How’s it all work?

      So you’ll occasionally see two white lines perpendicular to the road at a set internal. A helicopter, drone, or plane can time when a car passes both of these lines and can calculate the average speed of the car.

      This info is then relayed to a police car on the ground who then pulls over the driver.

          shrugs

          Less likely to be noticed by drivers or alerts like on Waze. Probably a bit more costly though if they’re using helicopters or planes instead of drones.

              Deterrence. You never know when they might be monitoring you above, so watch your speed.
