I think mapillary may still be right. I rode on this just yesterday(!) and didn't notice any bumpiness, but that picture looks very familiar. I'll change it back again until I visit that area again.

Thankyou!!! That makes it a lot easier to follow! So that is where State Growth make their edits, I suppose. I'm not clear why these don't migrate into other layers.

Thanks for the tip, I'll make some edits :)
