Uh, yes: consumer test of helmets always involve neck breaking experiments! That's why they go through some many testers!in fact a lot of the tear drop shaped helmets are worse for you then the round ones because the tear drop shape and other odd shaped helmets don't allow the head to rotate and instead snaps the neck. This why time and time again round helmets fair better in consumer studies...of course no one likes to wear round helmets and they are a bit a of pain to find.
Seriously: you are insane. No helmet is THAT dangerous - a teardrop shaped helmet is still made of foam and tear apart from a fraction of the energy need to break a neck. For any TT and triath readers: NO ONE HAS EVER HAD THEIR NECK BROKEN THIS WAY; THIS MAN IS A LOONIE! So you can go wearing your $500 hat and cutting your times by 0.5 of a second.
