Hahahaha! Your reaction to that rear slip You gotta laugh those things off. I'll admit I'm pretty reckless on a bike, but damn, I felt nervous watching to ride while talking that whole time. "Is he even concentrating ?!" lol
Just a thought on weaving back and forth to heat the tires. That actually doesn't create much friction for introducing heat. Several hard accelerations will warm the rear up nicely, and several hard brakings for the front. You probably know this anyway.
Makes sense on the music. It's just that I see a lot of videos where people throw in music just because they want to. Man! I just noticed that dude @ 0:40 on the recumbent just asking to get creamed from behind on a tight road like that. (flag or no)
