Smart mapping: Size is not always the only criterion deciding whether to map an Area or Point Place. We can think a bit further, especially from the driver's perspective. A building hidden in the woods might be large, but neither significant nor distinctive, as it won't help the driver orient during the drive; instead displaying it might have him wonder if he is on the correct route as he doesn't see it from the road. The same goes for a water treatment plant: it may be large, but probably not recognizable from the road. So even though being large, we only need them to show approaching our destination and they can be mapped as a Point Place as well.
