I can't see the video but is he at least smart enough to drive this death trap on a closed track?
Nope, he drives it on bike paths and sidewalks.
I think the concept is pretty interesting, but the implementation is complete crap (even for an early effort). Think of playing laser tag with a helmet where the helmet overlaid your enemies to make them look like zombies or aliens. Or, how about playing Mario Kart on a go-cart track so you could actually race Bowser.
The military stuff is already available, but it's more for overlaying threat indicators on a heads-up helmet display in aircraft for example.
