That road is a LOT like the tiny, 2-lane, landslide-prone road from Taipei to Hualien...

(you can see part of that road there, that liiiittle brown strip along the cliff.)
and also a lot like the road through
Taroko Gorge. (number 4!)
eta: and yes, i've been down BOTH those roads. Well, not DOWN, but.. oh you know what i mean.
