My error - a quick glance during a drive by (as a passenger). I have removed it.

Thanks for the feedback and for updating the tags on the object.

Hi Mike, Thanks for your feedback. I have set designation=byway_open_to_all_traffic and removed the access tag as I as can't confirm (wiki)"ALWAYS add known access rights" I can only assume access to everything based the Byway sign?

Do you think these are dummy postcodes the council generate for their car parks? I'm happy to remove them if you think they will appear as invalid on any postcode analysis.

The postcode is displayed on the car park sign. A bit strange as car parks aren't really a mail delivery point?
