Many false positives are generated because aerialway=* and piste:type=* are not taken into account.

I stumbled upon a few cases, where narrow sport tracks were correctly mapped as ways with leisure=track, which led to false positives, because every object with key "leisure" is considered an area. I've therefore changed the condition to

if (tag.attrib["k"] == "area" and tag.attrib["v"] == "yes") or (tag.attrib["k"] == "leisure" and tag.attrib["v"] != "track"):

Often mapping tracks as a way way means looping back to the start, forming a closed way closed way (the shape of many racetracks). It is tricky as this tag is also being tagged as an area - that can also be represented by closed ways.
It's unclear/undecided whether closed ways should be treated as areas for this tag so it is advised to always add an area=yes/no tag in the case of closed ways. The default OSM Carto stylesheet displays an area only if area=yes is present. This is not necessary for multipolygons since they are always handled as areas.
