While you are quite right about all this, Vince, still it seems that the primary 'danger' factor (other than rider skills)is speed, and survivability means moderate speeds. You make the point that a number of factors could have been involved in Masters' crash, and I think that is the point - there are so many factors that could be involved in causing a crash, but the crash itself is far more likely with immoderate speed, and having crashed, survivability is far less likely too. With our cranky old British born bikes, excessive speed is far less likely because even going at reduced speeds, the bike itself will allow you to know how fast you are going. If I go 50 mph, which is maximum for me (40 is more likely for me) I can feel that I am really moving. It is very noticeable.
A corollary is the rental car I once drove from California to New Mexico. Prior to that drive, my vehicles had all been trucks and four wheelers, and all sort of clunked along. But there I was cruising on the straight and narrow when I happened to look at my speed and saw that I was effortlessly cruising at about 80. I believe it would be the same with some of these tour bikes.
Well, morality and common sense can't be legislated in, but I, for one, will much more appreciate a bike that lets me know when I am exceeding my own, and its own, limits!
