I agree. I suspect that the post town / dependent locality are correlated against the post code by the OCR processing. If there was no post town it would seriously degrade the scanning accuracy as the postcode OCR would need to be 100% accurate, which is not going to happen given the number of

That's why RM have a Dependent Locality, to distinguish between cases like this. If the OSM addr:* tags are to represent postal addresses (and that seems to be the consensus) then OSM should offer a place for the Dependent Locality. RM say the Post Town is a mandatory component; why do you

Hi, Great! Don't worry about having "too many nodes" - the OS data is already generalised a bit (I think they target 1:1) so it could be a lot "worse". I spend a lot of time curating the admin boundaries; occasionally I will update a bit of coastline from OS data when I am "in the area".

I also have a couple of observations about these changes. 1) Sometimes an admin_centre is being added to a boundary=political (e.g. parliamentary constituencies, electoral wards). I am not sure this is appropriate. 2) There are multiple definitions of "town", and I don't know which definition

The term "HGV" is not actually legally defined in the UK. Goods vehicles start from 3.5T MAM. There is a special driving licence group D1 which allows you to drive up to 7.5T, but the difference is in the licence, not the vehicle. The sign with an image of a lorry is used for a so-called
