Season 49
About the Episode
Some traffic jams seem to happen out of nowhere—it’s not rush hour, no construction, no accidents. These are called phantom traffic jams, generally caused by drivers tapping the brakes on and off. Could autonomous vehicles eliminate these traffic jams, and make our roads safer? Some researchers think so.
