While I suggested the value "opposite" with the same reasoning as Pieren
i.e. to guarantee this tag is used on ways only when necessary; the truth
is there wouldn't be any guarantee because the values "left" and "right"
still exist (though theorically only for countries).
The advantage of *not* having "opposite" as a value is not to need to
verify the country's driving_side to be able to tell which driving_side
that way has.
Since we need to use validator rules anyway, we could use:
1. driving_side is only allowed ways that belong to countries that have
2. driving_side (on ways) must have the opposite value of the driving_side
specified in that country.
