With visions of Top Gear's trip to the Transfăgărăşan still fresh in my mind, I discovered this amazing blog post about the 19 most complex and dangerous roads in the world.
My favourite? It's a toss-up between El Camino de la Muerte (any road that actually calls itself "The Way of Death" has to be taken seriously) and the frankly insane Guoliang Tunnel Road, which makes my drive home around Chapman's Peak seem tame by comparison.
