Magnet Bus

Earlier this month, researchers performed a test run of a bus that basically drives itself. It follows a line of magnets embedded in the pavement, coursing exactly along its route and eventually to the bus stop. The tiny magnets on the bus and in the street guide the bus to the perfect parking position at the stop for picking up passengers. It's a cool idea, and a lot of transit agencies are interested. But there are wider applications. Take, for example, my neighborhood, where nobody knows how to park.
