Very true, but were I to wear a helmet or neck airbag helmet I probably wouldn't wear one that was objectively worse at protection than another. I figure if I'm going to look like a dork either way, might as well go with the safest option?

If there's data to prove it's just as safe as regular helmets (which right now aren't tested very well either, if memory serves me correctly the only test required is to drop a weight on the helmet at height) then I might be less critical, but I still think the forehead protection looks a little shoddy on the surface.
