This is why I said that a full description that is useful to everyone would require many more tags than we currently have (about 6 or 7 as far as I can imagine). Note that the way in this picture would be classified quite differently for each vehicle type (pedestrians, and maybe bikes to some extent can do just fine on it, but not wheelchair).
I would tag this one as this: surface=asphalt tracktype=grade1 (grade2 says unpaved-only and says nothing about potholes) smoothness=very_bad mtb:scale=1 sac_scale=T1 (or maybe T2) wheelchair=limited But I think different people would disagree on whether we should render that as a 'good' or a 'bad' road. The potholes would likely be temporary in many countries, but not so much in others. So maybe the renderer should consider all tags except surface and draw the way as 'bad' if it is ever bad for someone (car, pedestrian, cyclist or wheelchair user).
