I think it's safe to assume that two ways on different layers should allow the users of the lower layer to pass under the users of the upper layer. I would presume that the cars can't drive *under* the tram tracks, so therefore they are on the same layer. You could politely encourage everyone to figure out where the bug in the rendering is, and either file trac ticket or submit a patch. The more details, examples, clarity of explanation and so on the better.
