Mxsmanic,

And the absence of data is still there.


Says who? You didn't ask for data. You asked how it was taught. You got
an answer.

You have not provided any factual basis for any "absence of data". You
have also not provided any back-up to your claim of motor cycle turns
being the same as airplane turns. And you haven't backed up your claim
that motor cyclists are actually taught the way you claim they are.

So, if there is anything absent here, it is any kind of factual
foundation for your blathering.
