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

Why is that better than the police officer who was going to pull them over just using a speed gun?
I drive through areas like this all the time for years. I have never heard of anyone actually getting a ticket from this.
