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.

Why is that better than the police officer who was going to pull them over just using a speed gun?

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.
