I do believe that the peripheal senses (not just vision, but spatial awareness, and proximity sensitivity,etc)
are limited and distorted by helmet use. The deprivation caused can play with the gyronomic equilibrium of the head/body relationship. This is the key to balance, which in turn is the basic dynamic principle of riding a bicycle.
Explain? How does a couple hundred grams on your head which blocks neither your ears nor your eyesmess with your "proximity sensitivity" or your "gyronomic equilibrium." What are these senses and how are they effected by the helmet. If you are talking about your vestibular system I don't see how an external helmet could effect the functioning of some fluid filled tubes and little weights. If you are suggesting that the helmet some how effects you the acoustic properties of your head and therefore your hearing I think it is safe to say that traveling at 20mph effects them alot more.
