As you are talking about rendering of the roads. I am actually looking at this for the new cartoCSS mapnik style for osm.org. Currently we have several omissions in the mapping for level 18. I think 'all' roads just use the width for the level17 zoom. This is unrealitisic and misleding. I am wor

I would see the root problem in the fact that osm has bigger scope that most other maps - from low detail overview maps to very detailed (almost aerial photograph level) city plans. Describing physical area occupied by different features seems to me like the only perspective possibility - With the

You can always make a rendering with the streets drawn wider at zoom 18. That would solve most of the problems. Mapping all the street as a series of parallel lines or areas will just make a large mess of data that is a pain to decipher. It only really adds value at very high zoom, and it isn't a

Hi Martin, I must agree with you about the lack of simplicity of this relation-based model. I've been looking for a better and simpler model before updating the proposal (because I'm not a big fan of relations since it's an abstract object and we don't see them on maps), without success. Even if
