> Coming out of Georgetown drivers begin a long, steep incline up to the tunnel. As you climb the last few miles to the tunnel, the speed limit drops from 65MPH to 55MPH and you have some folks who instantly do the -10MPH acceleration and you have others who don't think that they need to slow at all.

But that part of it you get anyway, because you haven't come to the exit for Loveland Pass yet.

Also note that the driver took a route almost a thousand feet higher (and probably less well plowed), when deeply worried about snow and ice. That sounds... rather odd.

I mean, I'm sure he had what to him were sufficient reasons to do what he did, but the stated reason seems somewhat inadequate.
