Fair enough, though as far as I know it's never stated anywhere else that oneway=no is the default. Certainly it's not on the Key:highway or the Key:oneway page. > Note that the "implies oneway=yes" in the right column wasn't added on > the page until June this year.

So there's a seven month window in which it could have been taken to be oneway=no by default, though that was never stated clearly. > Hence the only option is to revisit all motorway links that don't have a > oneway value and add it.

Which there probably will be no matter what. I'd much rather have sane defaults and a slight inaccuracy then have to deal with insane defaults forever just because of a short window created by someone who made some bad assumptions. -Alex Mauer "hawke". _______________________________________________ talk mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk
