Just been reading the following announcement on the revamped Google Trusted help pages.
It seems Google have woken up to the increase in bicycle use and the need to map these specific cycle paths. ( I’m sure the same applies to footpaths too.)
They have published some guidance to work with your local authorities to add these cycle paths to Google Maps. Once the paths are on the map. Any GSV video mode captures that we make will snap to these paths.
See this link for the details -
