i second that. example: http://osm.org/go/0JhJe_3X5-

public should be a "P" without transparency
permissive: "P" should be transparent
private: "P" shouldn't be rendered at all, yellow area should be visible though.

If private parking isn't completely suppressed, it should be suppressed at higher zoom levels than public parking. Currently, there are areas, like Burnt Oak, in North West London, where people have mapped every single area with an array of parked cars (presumably from aerial imagery) as a car park (they haven't specified access, but that can be fixed after survey). This results in a sea of yellow, even if the P's are toned down once access is set.
