Unable to answer "How wide is the road here?" – Honeypot close (Residential Road) – https://osm.org/way/1251297310 via StreetComplete 59.3:

Road only to fit a fire engine (just) cars trying to pass each other to go up/down road at same time will have difficulty very little footpath (only up to 50cm) so even if cars pull onto it it is still very difficult to pass.
