The only experience I've had on The Dragon meeting a vehicle not suited for that stretch of road was a couple of years back. Coming home from Alcoa, TN I took US129 back to US28 and then home. Met a police escort for a mobile home on The Dragon. Cop warned me that the rig was probably a 1/2 mile behind him and to make sure I didn't meet the rig in a curve. Since I wouldn't be able to see him far enough ahead if the curve was a blind left-hander, on the next short straight section I came to, I pulled over to the shoulder and just waited for mobile home to pass me.
