So now you're telling me the police check speeding by eye. Jeepers !

  It's literally "start the stopwatch when the front tire hits the first line painted on the road, stop it when the front tire hits the second line (or some other predefined immobile point), and look at a chart to see how fast they're going." Usually radioed to a second car down at the next intersection.
