[Talk-GB] Useful or superfluous adding unmarked tactile crossings at junctions?

[Ken Kilfedder]

I've noticed that some foot routers (Android 'Guru Maps' is one example) get 'trapped' on one side of the road if there are no crossings in the dataset.   (So I've added a few).   The lesson is - don't separately-map sidewalks unless there are crossings too.
