Fuck Cosi, you're full of shit. Not everyone wants to drag their knee in every corner. Doesn't mean they should give up motorcycling. We don't all aspire to your hero level of motorcycling.
It looks like that "Tail of the Dragon" road has a pretty good surface and they were riding smoothly for the most part (with a couple of exceptions). The BMW rider's speeds were between 30 and 60mph (60-100kph) which is not blindingly fast. The highest speed I saw on his speedo before the camera flipped to rear view was a short burst up to 84mph (135kph). The guy on the Yamaha had to stand his bike up in a corner to avoid an oncoming car, and he did go very wide on one corner, right across to the other side of the road, which seems to indicate that he was pushing the limit of his skill. He was lucky there wasn't an oncoming car at that particular moment, but surviving by luck isn't a good long term strategy. If those guys habitually ride like that, sooner or later their luck will run out.
I just looked up the speed limit on that bit of road and it's 30mph, so the cops could harvest a lot of fines if they propped a speed camera on the side of the road!
Personally, I don't ride like that nowadays. It's a risk level I choose not to sustain. I might have an occasional squirt, but only when I can see the road surface far enough ahead, or I know what's around the corner (like on a track day). Out on a twisty road through a forest, you never know what's around the next corner, especially on the country roads in my neck of the woods. Things like a patch of wet road, bit of gravel, tree across the road, flock of sheep, etc. At my age, I prefer not to be bouncing off the road, or worse. Having to scrape a mate off the road last summer was enough to remind me how easily it can all go wrong when you crank up the pace.
So what if the edges of my tyres aren't shredded? It's only idiots with a "road warrior" hero attitude that see that sort of thing as a badge of honour.
