One thing is for sure, it would be a car killer for a lot of guys. Personally, I think they would avoid it just for that reason. I don't think Hot Rod wants to purposely lose a lot of the heavy hitters, because many of them would not be able to make it through. If you've never been on that road, it's a tough one for any vehicle.
On the other side, if I take my GT, I would LOVE to take that route.
