I'm not entirely convinced on that one. After making contact with, and likely sliding down the road, the odds of the bungs (covering the emergency release screws) getting mashed up and being impossible to remove is pretty high. Also I'm not sure I fancy the chances of the release mechanism, hinges etc. still being operative after a big hit. Or, come to think of it, staying locked in an impact. I'd guess that it'll also be a lot heavier than a standard helmet design. Unnecessarily complicated for me I'm afraid.
