osm.org/directions doesn't compute the ferries to England, such resulting in major detour via France (Saint Malo-Cherbourg) i.e. to Dorchester.
Please attach ferries properly to roads.

Is this done yet? GPS traces seem to show it being traversed "properly".

Can anyone investigate on the ground an amount of mini-roundabouts here? For now there are mapped 6 instead of 5, as I can see at https://youtu.be/DmvHZ4omB2A. And tracing is not accurate :(

This bar 'hot' does not exist - maybe the location is wrong.

Fairly sure there's a break in the road here (bollards & a curb)

Radlett Lawn Tennis and Squash Club

way/46040701 seems like a private golf course, can someone with local knowledge confirm that?

Can see some roads in bing here, and maybe some more golf related stuff? Needs survey

Major development in progress in this area. Please survey and update regularly.
