Cute.. though those accidents are all fairly low speed. Wonder how it would work when you're going much faster? If I am going to endo, it will probably be a lot faster than 10 mph.
Things I noticed.. it takes batteries, and has on and off switches. Typically my neck is not uhh, dry when I'm biking. This thing would be soaking wet by the time I got anywhere. Wonder how it works when soaking wet?
It weighs as much as 3-4 normal bike helmets, but maybe it would be more comfortable since it isn't on the top of your head?
It would probably be more stylish than a bike helmet if I was lady gaga or had some sort of euro chic fashion sense.
It costs $451...
Here is a google translate from the company that makes the thing:
