It's very clever and it is possible but I have to break the news that the wipeout video is a fake, sorry guys the first one is real though, but the CGI in the wipeout one is impressive.
The quantum levitation is what was really cool to me and I have never seen it before. They should make the roads with magnets and just make a special gas tank to hold liquid nitrogen to keep it col all the time.
The first vid is a real thing that happens. I am not sure about the second I just saw it as well and it seemed cool since it is the only vid I saw where it was something other than a metal circle.
