This is kinda like the Red Mountain Pass discussion - both of which have been on here many times. Basically, it boils down to evaluation the facts and your comfort level with them.
Driving on a two lane road with little to no shoulder and with curves, grades and little or no guardrail is, in my mind not safe.
And remembering you have no control over the idiot driver coming against you or the person passing you and cutting back in....those leave you without choices.
I just spent a week in Ouray and up to Red Mountain Pass several times for photographing and just the Fall beauty. So reminded of these kind of conditions / situations.
So, evaluate for your personal decision.
