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.

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.


(In a perfect world, a road would be not a line, but a
polygon, so the width and area could be perfectly known).
