Lol. That is the famous "sea to sky" highway. You should have seen it before the 2010 olympic upgrades. It is a runway compared to what it once was. It isnt really a mountain highway but a coastal route. It follows a train track most of the way. You all know it. Something like half of north america's car commercials are filmed in vancouver, and many of those use the s2s.

I used to ride it several times a week on my vfr. The real rollercoaster starts north of whistler: the dirty dusty duffy lake road.
