There is a massive difference on OpenStreetMap between inaccurate and accurate, but incomplete, data. Stub ways showing the direction of service roads entering & leaving car parks clearly fall into the latter category. They have useful information, and are not wrong. I would politely ask the people removing this information to desist: they clearly have a less clear picture of the situation than the original mapper. I'm afraid it's a case of blindly following a false positive from a QA tool. They should also be requested to revert edits which have removed valid information from OSM. It may help to add other tags, but I would suggest following a couple of fairly widely used conventions by adding a [fixme][1] tag: - Add `fixme=continue` (not "continues") on the last unattached node of the way. - Add a `fixme=stub for further survey` to the way itself. A much less used convention would be to add a further way connecting entrance & exit purely to illustrate the correct connectivity. This could be tagged `artificial_path=yes`, which has been used for rivers/streams passing through lakes and reservoirs. [1]: http://wiki.openstreetmap.org/wiki/Key:fixme
