I've not seen that kind of pullout. Well of course I have but they aren't designed for a slow moving vehicle to let traffic pass. They are just for safely stopping. Like fishing something out of your back seat, taking a quick break, sometimes there's a vista there, that kind of thing.

The turnouts designed for slow moving vehicles to let others pass, at least to my experience these are almost always signed far enough in advance (I'm sure there's a vehicle code mandating distance of signage) and they are at least ten or tens of car lengths long.

I think you are asking too much for any vehicle to pull out into one of those tinier kind of little turnouts for the sake of normal kind of driving/passing activity.

Agreed and this is why i would never use them were I driving an RV, and I don't blame others for not doing it. I'm just noting that I see the big trucks do this all the time. I'd estimate once a month I end up behind slow car panic stopping when he realizes the truck isn't having it.

I've driven just about everywhere west of the Dakotas. You're talking about the kind that's sort of like a new lane opening on the right, going parallel with the road for a good while, right? Those are incredibly rare, I think mostly in one region of California, like maybe the Yosemite area.

Ignoring those clearly-marked, friendly, and predictable pullouts, practically everything else is a total crapshoot you really don't know what it's going to be like until you've already driven past it. With a 38-foot 31,000 lbs class A, we made it the passenger's job to call out whether a pullout was safe or not, because the driver just didn't have enough time to notice it. Often we did manage to pull out of traffic for a moment and let 3-10 cars pass, but sometimes it just wasn't feasible.
