Then the sandbox usually gets a year or so of experimentation. During the experimentation, people take it in whichever way, like the self-driving tricycle: people kept thinking it’s a shopping cart, so people actually tweaked the program into a shopping cart that follows people around. You can buy some flowers and put them on the shopping cart. It follows you around and forms a fleet once it’s full, and you can ride on the first one, and it drives you home. This is something that the MIT Media Lab obviously did not think about when they designed this vehicle, but the local people seem to think that it fits their needs the best.
