FWIW, that section of roads north of Glasgow up past Loch Lomond and over Glen Coe is an absolute horror show for bad driving. I would certainly not want to cycle over Rannoch Moor and down Glen Coe, whatever the views look like.
Can also confirm this, I remember driving over there a few years back and seeing an oblivious caravan towing driver miss a cyclist by about an inch.
It's probably better at night.
