"There are lots of clues that give us reason not to get our hopes up this time. Every hover device that relies on superconductors only works on a special magnetic surface, and this board appears to be floating on concrete at a regular old skate park. The video also doesn’t actually show someone riding it, although Lexus has promised more videos of it being tested, just not right now. So what do you think? Is this just another publicity stunt loosely based on existing science? Or has Lexus actually managed to get a working facsimile of Marty McFly’s second coolest ride?"
