Congrats on living in this wonderful region
The problem you are referring to is well known - it's the conflict between those focussing on the breathtaking panorama while driving (hence they drive very slowly and don't observe what's going on around them ) and those others who focus on the driving pleasure on these roads.
That's why I recommended to avoid the main summer holiday season. I can understand that it's a pain for you to encounter the "panorama guys" on a daily basis
