Okay, so it wasn't just me, that bike went from straight line to sliding down the road much faster than it would have if he had lost control. Sure seems like it was tossed down intentionally.
And heaven help me, if you see me sliding down the road, something is seriously wrong, because I've said it before, and will say it agian, I'm not looking forward to skidding down the road on my ass. In fact I'll do everything I can to stay upright. That's just my chicken, self-preservation side showing, though. Some people sure don't seem to have much self-preservation left.
