Welcome to the future. If you are flying through London’s Heathrow Airport, be on the lookout for the UltraPRT pods, little electric vehicles that run on a closed road, taking passengers from terminal to terminal, all with no driver. And Heathrow is not alone. A town in Buckinghamshire is about to get a fleet of taxis that follow a similar model. Google’s autonomous research program has a fleet of very recognizable Priuses and Lexuses out on the road as well. The closed loop model used by Heathrow is how this technology will spread. Good stuff.
