Hi, I noticed something weird in MapFactor using the OSM.
When driving from Antwerp to the border with the Netherlands, along the A12 highway, there is a traffic junction, called Zandvliet, where MapFactor chooses to leave the A12 and take a parallel road. Yet, at the end of the parallel road it merges again with the A12. Following the A12 would be a much more logical and fast alternative here.
I looked at the OSM, but as a newbie in editing, I can't find anything wrong.
No speed limits were set for the side road and as far as I can tell it has the same speed limit as the highway, albeit only one lane, so in theory it could actually be faster.
I updated the parallel roads speed limits in OSM, so it should be in the next update. :)
