Say you step off a train in a new city and need to get to your hotel, about a mile away. Most taxi drivers don’t want to take people such a short distance. But with your luggage, it’s too far to walk.
Someday, there may be a third option: Urban transit systems built around small electric vehicles, or pods, that drive themselves.
Supporters of these driverless pods say they take up less space than cars, cut down on urban noise and produce zero emissions. And they offer more flexibility: Instead of relying on a set schedule, riders can summon these pods for private, individual trips.
