This goes in the "too good not to share" category. An airbag for your head, instead of a helmet. Because one of the things I really admired when we were in Italy was how glamorous everyone looked while cycling around town. There's just no way to look this stylish when you're wearing a clunky piece of polystyrene on your noggin. Plus there's that whole helmet-hair thing. So far this new technology is only available in Sweden, but we can all hope it gets to this side of the pond soon.
This video is worth watching, not only for the cool crash-sensing airbag for the head, but just for the pure geek factor of watching a crash test dummy endo a bicycle in slowmo.
