Firstly, I’ll quickly mention I’m totally against treating the problem like Bernhard suggests … not all of us have the ability to play with the style & type files to create these custom workaround maps. And as Beddhist states, we should be fixing this issue for all who use OSM, not just the computer savvy amongst us.
And Tom, you may feel this is anecdotal complaining … I assure you when you look at the FB stuff in the field, the errors are everywhere. I honestly feel we are just beginning to realise how much bad data exists out there. In the early days, we were spotting bad inputs, complaining, and supposedly the FB team were going to fix. I think the reality was they did improve, eventually, but never got to grips with fixing the older bad edits.
Yes, I accept the line between track and road may be blurred to some, but one thing should be clear, and its the focus of my complaining …** is it Paved or Unpaved** ? I could live with these 10-15 km “residential roads” that wind their way through fields and woods BUT ONLY IF THEY HAD TAGGED THE RELEVANT SECTIONS AS UNPAVED. At least that way, most routing engines would avoid them.
Facebook have offered to review, but its not being done quickly, or thoroughly enough … I see some roads being changed to tracks (or having the unpaved tag added) but then adjacent roads are left unchanged. Its a sort of dirt-dobber dance approach, in old USA parlance.
You will have seen my earlier post on the overgrown lane … well as I was riding in Lampang province with some time on my hands, I thought I would stop at a few more… and believe me, it doesn’t take long…
Way 538858336 : Marked as residential by Zvone, with no unpaved tag. Just look at it !

So then moving down to Lampang, in faceless Michael’s hurry to bang in a residential road (Way 537269623), he doesn’t bother to look at the road close enough to realise its actually a path way, with a locked gate between two walls. And to add insult, the changeset tag reads “Modified existing ways for better connectivity”. Are you telling me Micheal, that you just started joining up roads that look they just might connect ?

And almost everywhere, you will find find examples of driveways to private houses being added to the map, often behind locked gates too. Just one example amongst many, Way: 537465133, tagged as residential, with no access restrictions…

OK, while the latter may not be a big issue, the first two are. Need I go on ?
Beddhist is right - change every imported road to highway=road while we sort this bloody mess out !
And off-topic … Beddist, I have been doing the same as you … the main road through a village stays as unclassified, which if nothing else, should make the routing better.
