I looked at the video pretty closely. My first thought was the highway from Aspen to Independence Pass, but the road is not in that nice a shape as the one seen in the video. I even tried to see what some of the exposed geology was, it sort of looked like the grey mudrocks of the Mancos Fm, common in the Colorado Rockies, but maybe not. I even looked at the place where the car is flying off the cliff. It does not really look like anywhere in Colorado that I have been. Not that I have been everywhere in Colorado. It's not the Million Dollar Hwy, I've been on that road many times, on the bike too. It doesn't look like anywhere in the San Juan Mtns.

Maybe Montana or the Canadian Rockies.

I even did a web search and got a few hits of other people asking this same question but I did not see an answer.
