I've been on the Dragon numerous times... Anyone can be a hazard there and not just the cruisers. I've had cruisers in my lane several times, but I've also had some punk in a riced out import too many times to count.
This guy was carrying some speed, but I would guess that the speed coupled with his intent to wave to the photographer is what did him in.
I try to ride the dragon during the week and not the weekends. More space, less idiots.
That said, there are some fantastic roads all over down there and I highly recommend Rt 209 out of Waynesville heading north to Hot Springs. Also, one of the best to ride is "The Snake" which runs NW out of Mountain City, TN. Closer in towards Asheville and Charlotte, is The Diamondback and the Devil's Whip... Basically starts at Rt 80 out of Marion, NC.
Have fun, wear the gear, and stay in your lane.
