This looks so cool. Makes me wonder why don't all karting/motorcycling helmets do this? OK not really "why not all?", but I am surprised that i'ver never seen

  With the current state of electrical storage, doing this on some old-timey-looking goggles might actually be feasible.

  Maybe it works on the track, but for normal road use it's a really bad idea. Turn your head to one side at speed and the rotating disk gets ripped right off, if you're lucky!

  Helmets use a simpler system with disposable tear-off films.
