The gate blocks the private highway, and if mapped along with a link to a the nearby public road would be flagged as a highway blockage.  This highway represents less that 1% of similar private highways in this area a somewhat arbitrary addition to the network. Mapping all private highways and all gates / barriers is an option.  The adjoining property has converted the entire  front garden into what may be interpreted as 3 parking spaces - a parking lot, , but maybe one is a driveway and 2 adjoining parking bays.  The property opposite is similar, 3 parking spaces, nothing else, accessed across a concrete footpath and kerb.  Should not all driveways be mapped, along with their gates and any private parking bays installed?  A nice challenge? Or maybe private domestic driveways and parking bays should be left out as is the case apparently with domestic garden paths.
