It makes more sense - to me - to place nodes with their actual
latitude and longitude, so if the edge of the carpark is right here
where I'm standing then marking it in the database as being somewhere
5-10m over to my left seems wrong. Same with two buildings either side
of a road, where the edges of both are 10 metres apart, not touching
down its centerline.

This is because I'm in the "centerline" camp - those of use who
believe we're marking the middle of the road for expedience's sake see
no problem with a park - for cars or otherwise - coming up short of
the road. And it means that areas preserve their actual dimensions
instead of growing outwards beyond their actual boundary - an
increasingly proportionately large problem as we add ever smaller
details to OSM.

Cheers,
