I don't know it. It seems to be supported by the lack of evidence that racers do actually practice it. (It's also a implied suggestion to look at what racers, if anything, do to practice falls.)

Without any actual data, one would presume the proportion would be the same as that for the overall population (for which you appear to be saying that fall practice is low).
Also, why are collar bone fractures common in bicycle falls/crashes if "many of them have so learned some form" of correct falling?

No one knows. If it was so "self evident", it doesn't seem that odd to expect that they would already doing something about it.
