[OSM-talk] Divided roads proposal

Agreed, while it's sensible for two ways in a dual carriageway, it seems 
OTT to have two ways for a road simply because it's got white lines down 
the middle. It seems to me to be introducing unnecessary complication, not 
to mention increasing required storage size and bandwidth for transmitting 
the data or the need for pre-processing tools to remove it if you're not 
interested in it for your purposes.
