Personal Rapid Transit systems have been on the drawing boards for ages. Call up a small, personal, driverless, autonomous vehicle, program your destination, get in and off you go. Prototypes have been built but such systems have generally not gotten off the drawing board. Until now at Heathrow airport in the UK. Yes, the destinations are limited but watch how cool this is, and note how many buses and the level of emissions avoided. Nice to see a country taking the lead in infrastructure.
Hat tip to Gerd Leonhard for flagging this on Facebook.
Have a great weekend !
