Welcome to OpenStreetMap and thanks for updating the map.

Are these roads privately owned, but with access for deliveries and visitors and no thoroughfare? If this is the case, the tags you might want are:

access=destination
ownership=private

The iD editor presents access tags for other transport modes as if they were necessary, but you can and should leave them unset if the general access value already describes the situation,

There's limited street side imagery for The Drive and none for Pine Trees Drive, but the Bing Street Side imagery shows a non-standard weight limit sign at the junction with Swakeleys Road, which isn't legal on a public highway.
