Both the car park and the road exist, so it is unlikely that they will be removed. They are both tagged with access=private, so will not be treated as available to the general public for routing or parking purposes (this is why the road is shaded). Reporting the existence of a feature is not an "error", although tagging them as being public would be.

Were they to be removed from the map, it is very likely that they would be added again from aerial imagery, but without the access tagging.
