Do race cars have air bags? No! Why? because they are less effective than proper harnesses and helmets. I don't see how this is more effective than a proper helmet. However I can see how if you are too vain to wear a helmet that it may help.

Interesting but I think it will fail in the real world. Invisible? You mean that huge neckbrace looking thing? Maybe in the winter for commuting when you are wearing big coats etc but can you imagine seeing someone wearing shorts and a t-shirt with this huge thing around their neck? Yeah ..... No. Unless you wear a suit or dress on your bike apparently. LOL

Hövding is designed to protect your head in cycling accidents by detecting abnormal body movements. False activation of the airbag may be triggered by extreme movements when hövding is worn and is switched on, e.g. Jumps from
heights. therefore hövding should not be worn at disco or when stage diving
