Thanks for sharing, some interesting insights here for those not familiar with the topic.
From my perspective, and I use both the public infrastructure, and powered/non powered skateboards/longboards a lot; I'd say bike lanes, trains , underground , and busses, are great in terms of coverage and connectivity in caba and gba. They are patchy in terms of quality, but generally pretty good in my view. (Specially for the price!)
Personally I always wonder why people waste time sitting in their hot cars in traffic when they could be using trains for long distance and then cycling, electric scooters/skateboards etc for anything within 10 km. Sure, sometimes a car may be a good idea for some people and use cases (some notable ones like families with smaller children or disability related issues), but I suspect a large and significant amount of people would be benefitted and surprised trying the alternatives.
Cheers!
