Thank you, Bill! I actually wanted to know that. I'm not even being sarcastic. I was trying to explain this numbering system stuff to a French friend a while ago, and I didn't have the details right, which bugged me. It all seems rather clever to me. And I think it's quite reasonably vanagon-related, after all I mostly drive those roads in my van.
