Oh thank GOODNESS you’re doing this :) the history tab is so unhelpful because filled with worldwide edits that usually don’t even have any content in the current bounding box. Looking forward to this.

Dennis, this visualisation is SUPER-helpful! It led me to fix many wonky things: streets mis-labeled as footways, oneways going the wrong way, etc.

(Some things are unfixable, such as one-way roads leading into carpark buildings. It might be good to ignore sources/sinks that terminate it building entrances etc?)

I guess the computation is heavy, but are you planning to have the data refreshed? I have been hacking away at various patches, and it will be hard to remember what has been fixed and what hasn’t.

Interesting game! I liked the audio.
