Large neodymium magnet on the bottom will do it. Most are induction activated. They taught this in every motorcycle driving class I ever attended, along with the rules for legally running a red light.

That way you’ll also automatically collect all sorts of valuable metal treasures along the route. For free!!

No, it won’t. I invite you to get some large magnets and place them directly on the loop cuts in the street.
