Well, if this isn't done, then roads quickly become hairlines at lower
zooms.  There's not really much to look into. If you want to see the roads
they have to be wider than they really are.

What a professional road atlas would do here is very likely to exaggerate
the junction so that it makes sense given the width using to render the
roads. Doing this algorithmically is hard, but probably not impossible.
