OpenStreetMap
I hate those maps, they are full of shapes and roads. when they are imported not only online editor lags, someone also manages to draw some roads "out of sky" and they are hard to fix because of zillion polygons around :(
those objects make map look cool when rendered, but i know plain road schema is enough for routing.

That is why JOSM came with the option to filter data to edit. That way you can filter out all the messy shapes that would otherwise ruin your editing.
