I think Danilo made a valid point and if I would have to decide for one approach, I'd prefer mapping roads as center lines/ways as Simon wrote. I think there can even co-exist roads as areas and as center lines - as long as one still can do routing. With only areas you can't do routing without heavy preprocessing and (processing-ready) streets to me are one raison-d'être of OSM.
I too have been "in clinch" with both approachs recently.
Mapping large roads only with the center line gives the problem on where to place border objects, and when having multiple lanes where is the correct place for bus stops etc.
The drawback of areas is, that they are not routable. I think we should NOT loose all the contributors which have the main goal to mape a routable OSM.
I would suggest this:
- Always map the center line - If you have enough details and time to also map the area, even better
