- I mentioned, no less than three separate and distinct times in the posting
- you are responding to, that I was seeing a helmet as a liability at LOW speeds,
- and I went on to state (very clearly) that I was quantifying this as speeds
- less than 30-40 mph. I fail to see the parallel with a helicopter pilot, whose
- cockpit restricts his vision more than the helmet is likely to, anyway. I've
- got a friend that teaches Apache flying techniques - I suppose if you want to
- discuss the visibility from that helmet (which is clearly what you are
- referring to), I could ask him - too bad it has little to do with the
- situation of motorcycle riding.

- Concerning road debris:
-
- Now, I don't know about you, but I always wear SOME form of eye protection,
- whether it be shatterproof sunglasses, etc.., so dust and dirt (as you mention)
- are not a major factor any more than they are when you are walking down the
- street. For that matter, I've gotten dust and dirt in my eye when wearing a
- helmet, so that is not a major difference.
-
- I am very happy that you have some experience via a second hand source in
- the area of human factors engineering, but I'm of the strong opinion that it
- might be *easier* and more accurate to evaluate this first hand, as I have,
- rather than try to predict it based on "evidence" from an unrelated source.
