'Voorhees law' explains why the slower car often catches up

Many drivers know the feeling: pulling ahead of the slower car you’re stuck behind and driving down the open road at your own, faster speed. By the time you reach the next stop light, you’re sure you’ve left the slower car far behind you, but to your surprise, you see that same car passing right behind you in the rearview mirror. Horror fans may even remember scenes from “Friday the 13th,” where masked villain Jason Voorhees always sprints over his victims, even though he walks leisurely.
