I would say that in every thread that you spend time in, I still can't tell if you're a retard or a troll. And this one is no different. B/c you can't seriously believe what you're posting.
I've been road cycling, mtb/cyclo-cross racing, bike commuting, etc for way too long and have had my share of falls and have been hit by a couple of cars. In only a couple of times, did I have time to fall/land properly. And in some of those cases, my helmet has saved me from serious injury.
From friends and other cyclists, their stories are the similar, so I find it hilarious all of the garbage you are spewing here.
Then you suck? That is all I can say. I have had my share of falls and been in those same predicaments and have had more than ample time for my body to respond to land in the proper way. Just because you never trained for it doesn't mean others don't and can't accomplish what you suck at.
The chances of falling for an experienced rider in a normal bike commute is less like than have a tactical nuke land upon your head from an orbital strike. And I do mean an experienced rider that is taking zero risks. If you fall in that scenario then you lack proper ride planning and coordination. You might do well to even take a proper defensive driving course.
Even if you are less experienced, don't watch out of things that may cause you to fall while riding, don't safety check your equipment every time to make sure shit doesn't fall off while riding which may cause a crash, and so forth, then the likely hood of a styrofoam hat preventing severe brain injury from a mild fall during a regular bike commute is dubious at best. To think otherwise is to be a full brainwashed retard nor how the human body because both trained and untrained in a bike crash scenario that only results in the fall of the rider from a bike.
In higher risk scenarios, such as racing, stunts, mountain biking, and other such endeavors, a helmet WILL help prevent head injury. But again a styrofoam hat only helps disperse a certain amount of force and only in certain scenarios. A full helm would provide far greater protection in far more risky scenarios. To think otherwise is to even more retarded and you've demonstrated here.
Point is that styrofoam hats are mostly pointless for bike riders. Nor has there been any conclusive study or evidence showing otherwise in the decades they've been around. In fact, more studies show the additional harm they can cause than injury they may prevent. As I pointed out with the links in this thread. Unless you can come up with different studies that actually show various crash test scenarios such as how NTHSA does with car crashes, you are full of shit.
