So now we are well-fed and ready to go off to work. We have a wide range of transportation to choose from. We could hop into that old favourite, beloved of all 12-year-olds—the Flying Car, whether it’s the one boy scientist Tom Swift invented, or the Weasley car in the Harry Potter books. With the whole sky to choose from, road rage becomes a thing of the past. Of course, three-dimensional traffic, with ‘lanes’ stacked vertically, comes with a new set of problems, as Bruce Willis, playing a 30th century taxi driver, discovers in the Fifth Element. Alternately, you could use an Instant Teleportation Device—something we’ve all wished for at some point or the other. In this, you step into a conveniently located booth, punch in your location, and voila, there you are. As Larry Niven points out, this device could make instant riots one of the big problems of the future. Say there’s a riot going on, with lots of yummy looting. CNN beams this worldwide. Within seconds, looters can arrive from all parts of the globe, pick up a few goodies, stone the odd policeman, and zip back out to anywhere on the planet. Luckily for the rest of us, the police would have the same device, thus taking the concept of high-speed chases to an entirely new level.
