@Warin, Thanks for clearing up my confusion about passing places. These turnouts are definitely not the same. A vehicle should never stop in one. They are about 1/4 mile long and some but not all have painted lines to separate the highway proper from the turnout lanes. In the U.S., where we drive on the right, such lanes are always on the right-hand side of the highway, and although they aren't signed as one way, it's sensible to include that tag IMO. In practice, a slow-moving vehicle turns off the main highway, slows down enough to allow following vehicles time to pass on the left, after which it returns to the main highway.
Given that the passing_place tag defines the situation you describe, and indeed was created to model it, I'm not sure modifying its definition to include ways would be a good idea. In addition, the term "passing" or, in the EU, "overtaking", implies that the passing vehicle does so on the left (U.S.) while these turnouts are always on the right. Hence my reluctance to redefine that tag.
