All I own are Jaguars, so I'm quite aware of how a British car drives in the mountains. That particular road is a challenge, to give you an example of its steepness in my V12 car I start at the bottom at 70 mph, throttle wide open, eventually the grade pulls my speed down, it drops to second gear and I hold that for about an hour until I reach the top at about 45-50 mph. Once over the summit is's a wild ride down the other side!

It's actually very similar to Monty Pythons description of mountain climbing. " It's a tricky climb, its up, up until you reach the top and then it slopes away rather sharply..."
