Thanks for the tool. I tried about 10 in and around Khon Kaen where I live and map. All false positive. JOSM validator is handy, good and gets them all before upload. Think I’ll stick to JOSM validator.
Edit:
In Thailand there are a lot of highways obviously drawn by a major license change decliner from Bing without local knowledge. When I came across them during my mapping or my special cleanup of the Northeast I replaced them as time and local knowledge allowed. But there are still some or may be many which I left disconnected when enhancing or replacing major roads. They are unclassified, residential or tracks. They are sometimes disconnected, created by the disagreer and contain only or almost only nodes from the disagreer. I think they should be replaced or deleted in the automatic cleanup. Just reconnecting them would not improve the map but add to the expected automatic cleanup.
