Not sure about copyright on this?
Norman Dennison, director of Geographers' A-Z Map Company, confirms that Lye Close is a lie, which will now be removed. "The idea is to put something on the map to protect copyright," he says. "We try to put it in an area or a part of a road which would not be misleading to the ordinary person in the street. They have been put in out-of-the-way places."

A thought...
If you dont make [lower-resolution mapping data] publicly available, there will be people with their cars and GPS devices, driving around with their laptops .. They will be cataloguing every lane, and enjoying it, driving 44s behind your farm at the dead of night. There will, if necessary, be a grass-roots remapping.
Tim Berners-Lee
How is OpenStreetMap different?

Open source is the peer production development of source code for software that is made available for public collaboration.
The promise of open source is better quality, higher reliability, more flexibility, lower cost, and an end to predatory vendor lock-in.

How is the US OSM map compiled?TIGER Data: Topologically Integrated Geographic Encoding and Referencing system
TIGER/LineShapefiles are spatial extracts from the Census Bureau's MAF/TIGER database, containing features such as roads, railroads, rivers, as well as legal and statistical geographic areas.
