This road - the grades, sharp curves, hogback, no guardrails, etc - has been discussed many times on this Forum (see Search). One can pick sections to show - or not show - and there are all levels of experience, rigs, etc. The wild car, of course, is always the other driver. Going can be a detriment in some cases and, no, not everyone goes slow. There is never 100% in anything.
Like many, I am an experienced mountain driver and I would not recommend an RV driven thru there with an inexperienced driver. Clouddriver, with a 24 ft Minnie is about the same as me driving my tv.
Mountain driving always depends on experience, comfort and equipment for yourself and be prepared for the guy coming against you or the one that has to pass on the double yellow line.
