You could tag the roads with their width and renderers could render them accordingly - if they wanted to. This is actually only sensible for the highest zoom levels.

Re: [OSM-talk] buildings and roads
Or literally through the building ! http://en.wikipedia.org/wiki/Gate_Tower_Building This case is also interesting when it comes to tagging layers. what takes precedence in rendering, the road or the building?

Plenty of those examples. http://en.wikipedia.org/wiki/Pulteney_Bridge is a good one. Its easy enough to create if you make an area and give it the bridge tag. The building/buildings then sit within the outline. Then it just needs some more styles adding to the render style sheets.

Surely this is just a great example demonstrating that catography is harder than it seems at first sight. The problem is that the roads are not draw to their real width and therefore the building must be nudged or shrunk so as not to collide with the super-wide roads as rendered. What we should not do is move the building outlines on the ground to make the rendering work, as far as I am concerned it is a rendering problem even if it is a hard one.

[OSM-talk] Buildings and roads
Wow, Naga City is full of buildings. How did they get so many? Are those all building=yeses? Crazy. And I thought adding all the industrial and commercial buildings was bad. Anyway I still think that if the building layers were set at a lower layer level by default and the roads to a higher, it might look better.

If > the road layer is on top this won't happen. A "major road" doesn't have to be wide by default. I hereby invite you to visit Guadarrama, where a trunk road (the "N-VI") has only two lanes, and buildings are just one meter away from the asphalt. Yes, I agree that the rendering is messed up at low zoom levels (see Naga City in the Phillipines), but at higher zoom levels, I see no other easy solution.
