Yep, this is a bit of an issue. There's a road near me in Manchester where the road has tram tracks on both sides of the road, but cars and buses can only use one side of the road (so it's oneway for cars, but two-way for trams). Given that we may be aiming to have one way per tram track anyway (or at least that's what I've been doing where there are reserved tram tracks), I 'solved' this by having two parallel ways, both marked with railway=tram and oneway=yes (in opposite directions), but only one of which contains an additional highway=secondary tag. However it's not ideal as it looks a bit odd in renderers, and which way should contain the road name? Peter Miller has been advocating for trams having separate ways to roads, but simply re-using the same nodes where the tracks are in the roadway. This is a bit awkward to use in current editors (but not impossible), however it solves some of these issues, and a few more (like wanting to add separate operator=* tags for the tram tracks and the road). Given that we generally only use one way per road (rather than per lane), I guess that generally we shouldn't be adding one way per tram track when the tram tracks are embedded in the road - (use tracks=2 instead?).
