[OSM-talk] Editing road geometry Australia

[Maarten Deen]

I agree that Markus' solution is more elegant (and I was more looking to 
the offramp itself). I would normally also map it like that but I also 
don't go out of my way to correct situations like that.
The way it is mapped now is more organic, more as you would actually 
drive. As such I don't see it as wrong.

I would not add a turn restriction. For routers it is useless because 
you never get that route anyway.

Regards,
Maarten
