When should separate ways be drawn, and when should lane tags be used on 
a single way? In this intersection the asphalt is continuous between 
parallel lanes, but they are separated by long rubber strips with a 
cross section about 20cm wide and 10cm high - not something a router 
should expect people to drive over. Should these be separate ways (as 
this intersection has been drawn)? Or should lane tagging be used 
instead? See the yellow hump between lanes in the bottom of the photo at 

As for changes, I'd suggest removing 
<https://www.openstreetmap.org/way/703254763> and 
<https://www.openstreetmap.org/way/703254777>. Some turn restrictions 
could also be added, but many restrictions are not required as the ways 
are all one way.

Andrew, are you familiar with this intersection from travelling through it?
