2) In cities and towns where two-way streets are exceptional like Barcelona or Madrid, are people expected to tag them "no"? The motivation for this question is that there seems to be the convention not to tag them, and therefore you cannot tell the confirmed ones from the untagged ones.
As Peter pointed out, oneway=yes (or in the exeptional case of oneway against the vector of the OSM way, oneway=-1 ) is mandatory if the road is a oneway, for most categories. oneway=no can help other mappers to show it has been checked in areas of high oneway density.
