I don't think that he is an idiot to be honest, I've seen a lot worse drivers than him! He knows his bike well, but he isn't crazy if you watch again you will see that he knows how to brake and when and also won't overtake if the car is indicating!
I've seen people overtaking me on shitty cars only because I did 60 mhp on a 60 mph max zone at night in a heavy rain and the road wasn't even straight - now that is what I call f*cking idiot!
Your entitled to your opinion but im my opinion anyone driving in that manner is a COMPLETE IDIOT. Whether or not he knows how to brake is irrelevant. There is no doubt in my mind he is a excellent driver and is well capable of handling that bike but that does not change the fact the he cannot see the future and therefore doesn't not know what 'MIGHT' happen
