That guy is a fellow member of the German Tenere forum. The video is from his trip to the Cevennes, a very rural mountainous region in Southern France. I understand he was filming the whole trip, and that video is a compilation of bloopers. BTW I find it true that the GoPro Hero HD (which - like me - he's using) dramatizes the speed and makes the roads look much narrower due to its wide angle lens. And that Swiss RT rider at the end is taking his head off to the Tenere guy.
