The Medieval Streets of England

Over the last few months I have written a number of blog posts,
in which I have developed a theory about the spatial distribution of Streets and Roads in UK towns and cities.
Thanks to a recent development by Mapbox I have now been able to tie this theory together and illustrate it in one new story map, which I'm calling The Medieval Streets and Modern Roads of England.
In December Mapbox introduced 'in' expressions to the Mapbox GL JS. This new feature allows you (for example) to color roads on a Mapbox map by their type (road, street, close, boulevard etc). This new feature is perfect for illustrating my theory that you can tell the age of UK towns and cities by the spatial distribution of 'streets' and 'roads'. It has meant that I can create a new map with all roads called 'Street' colored one color and all streets called 'Road' colored a completely different color.
On my Medieval Streets and Modern Roads of England map all roads called 'Street' are colored red and all streets called 'Road' are colored blue. This means that it is very easy to see the spatial distribution of Streets and Roads in UK towns and cities. If you explore the map you will find that most UK cities have lots of red Streets in their historic centers, while outside of these city centers, in the more modern suburbs there are lots of blue Roads and very few red Streets.

Are you querying OSM live? Would it be useful to get a data dump and clean up those instances, or the query itself so it only looks for 'St' at the end of a string? I guess we'd have to lobby mapbox to allow regex rather than just 'in'?
Neat findings!
