This is nonetheless correct mapping!

 

What you are seeing it the resulting impedance mismatch from using linear ways 
to map what on the ground are actually areas.

 

That sort segment at a sharp angle only exists for connectivity purposes. And 
the data makes perfect sense when seen in the context of all tagging around it.

 

Please look at this:

as you can see from the dotted outer lines on that “connectivity” way, it’s 
tagged as placement=transition

 

That tells any data consumer that wants to care about it that the position of 
the way does not actually reflect a fixed relation to the area of the way.

As I’ve said before. OSM is not a map. It’s a geospatial database. A data 
consumer that wants to draw a map is able to derive the necessary information 
from the totality of geometry and tags used.

Hello,

Things have escalated somewhat:

Yeah, we now have the situation where turn left slip lanes have been mapped as 
sudden sharp angles, rather than gradual turns, which just looks wrong!

Thanks

 

Graeme
