That's reality, though. Real reality, not the fake reality on so-called "reality TV" (which I've stopped watching). Conflicts and disagreements are inevitable when there's that much at stake, and it's obviously being seen from his viewpoint, not theirs. I'm sure Tom Sykes would have had something different to say about a few things in that book ...
Nicky Hayden was indeed special (RIP). But even he couldn't make the CBR1000 work - as far as I could tell, he only beat JR once - at Sepang, in the wet. I don't recall him writing an autobiography - I don't think he ever got the chance - he was obviously a piece of the story in the "Faster" series.
