That sounds like a passing lane, we have those too. Those are usually nice although occasionally they are only long enough for 1-2 cars to safely pass. It doesn’t help that slow vehicles seem to often speed up for passing lanes.

But a pull out is just that. It’s a pull out. They are typically very short such that one has to pull in and fully stop. They are often found are on narrow roads in windy coastal, mountain or river canyons where putting in a passing lane is not feasible.

I don't know why anyone would expect a vehicle to pull off onto one of those just to let people pass.... So weird. I'd expect that to only be for someone who actually wants to stop and take a rest or something.

Oh I dunno maybe because it’s courteous and not selfish, or maybe it could be because posted signage often informs drivers that it’s Mandatory for slower vehicles to pull over if x number of cars are following.

Yeah why would people expect anyone to do that?

An RV driving 50 doesn’t seem like a big problem to drive behind.

I guess I expect people to be reasonable, but comments in HN should have taught me better by now.
