I don't think I said that, all I said was "according to taginfo it is used
only *once* on a relation".
If people aren't going to use it, I intend to restrict it's use to streets.
It seems it wasn't formally proposed anyway.

I don't see why there should be any distinction regarding the driver's side.

One more thing: this only makes sense if there is no physical barrier

The streets I mentioned do not have any physical barrier. Also, there are
some signs indicating they use an inverted driving side ("Mão inglesa")
This is one of these streets: http://www.openstreetmap.org/way/266622965
