Hi,
Thanks - Roseden Way is now opened up, so routing will start to work with OSM data.

Sadly, RM use their own proprietary PAF *location* data even if they display it over a OSM map layer.

Similarly, I can always tell who uses Google Maps, as they race past me to the centre of the *entire postcode* centroid and have to start looking at 60 homes! 

Sadly, algorithms don't fix local knowledge. :-(

The best 'fix' for a new build is an A4 black and white number / street/ post_code in the window. The glass or metal signs developers install are sadly mostly invisible at night.

Happy Mapping,

James
