some good news - in the centre of London, cyclists are on track to outnumber motor vehicles (cars, buses, lorries) within a couple of years

anecdotally it has got a much more pleasant place to walk around in the last decade

@jofr yeah, Paris has improved so much in the last decade. I made a map a while ago of car-free households there https://o.blanthorn.com/france-iris/map/#x=2.34&y=48.86&z=12.23 and you can see that the richer west of the city is dragging its heels a bit

@bovine3dom nice choropleth map! How did you do it? Leaflet or Plotly?

@jofr thanks :)

https://github.com/bovine3dom/france-iris it's tippecanoe + deck.gl + maplibre (+ perspective if you click the graph icon in the top left to mess with the data)

deck.gl is generally more performant than leaflet but the main reason I'm using it here is that you can use CSS layer mixing to make the base map punch through the colours because it renders as a separate layer on top of the map
