This is why I've largely ignored the DfT data. It just isn't accurate 
enough to blindly copy into OSM ad hoc. I enter cycle lane data such as 
this only when I have been to an area & actually seen it, which renders 
most of the DfT info worthless.

I've even seen data for NCN 4 that's illegal where it suggests a right 
hand turn but is explicitly denied by signs.
