MIT and the National Research Foundation of Singapore recently tested an autonomous vehicle they developed together. No, it's not a car or a truck -- it's a golf cart. The researchers created a self-driving golf cart called SMART and deployed several at a public garden to drive 500 or so tourists around during a six-day experiment. Since they crafted a whole system and not just the autonomous vehicle itself, they also tested a booking method which people used to schedule pick-ups and drop offs. In the future, that system could be adapted to a mobile app like Uber.
