Part of the problem is a lot of folks have never had to follow themselves up or down these tight stretches of Highway one. I would love to show them video shot from behind as they repeatedly cross over the double yellow line and kick up dirt with their rear wheels in the tight turns. Of course the fact that there are 7 vehicle backed up behind never seems to be an issue either.
The simple fact is that there are some roads like Highway One that are not engineered and or maintained for amateurs driving large RV's. If you cannot keep your rig between the lines and off of what little shoulder there may be you have no business being on that road. Sadly, lots of people "think" they are far better drivers than they are.
Feel free to disagree but once you have had the thrill of coming around a tight blind corner to find a 40' Class A 6' into your lane with nowhere to go you might just rethink your opinion. Been there done that. :R
