I don't see the point of editing just for consistency. Developers should
handle leading/trailing spaces, or the lack thereof, and different
capitalisation, as without any input validation the data will always be
inconsistent.

I am also curious about this. There is a dual carriageway near me that has 3
roundabouts along its length. Two of the roundabouts have signed 40mph
limits but the third one has no signed limit. I assume the limit for that
roundabout is 60mph?
