Re: What to investigate
In the big scheme of things, the RRW headline is correct, but issues of what he hit, how he was handled, decision to red flag and all that are someone else's responsibility -- Honda Motors concern is properly with determining if something with the bike caused, or contributed to the crash. I am sure the decision to go with an independent group as opposed to doing it themselves is partly to provide accurance to the other Honda GP pilots, as well as the general public, that there is no cover-up.
Issues of location of barriers, as well as procedures for care of downed riders etc are withing the scope of the new riders' committee named at Phakisa this past weekend. (of course, the fact that Honda own the Suzuka track gives them some responsibility for that part as well).
I personally am disinclined to believe that Honda would cover up a design or fabrication error if it were found to have been a factor in Kato's crash, but the traditional Japanese corporate reticence does serve to reinforce the "conspiracy theorists" out there, and it probably was a very prudent step on their part to name the independent commission.
