Even if you think what you would say is obvious, please add. This is genuinely something I think makes sense regarding local bus routes given the longevity of light rail and how infrequently routes change, but I also suffer from confirmation bias, so I’m hoping for reasons this would be a terrible idea but obviously would prefer reasons it would be an even more amazing idea than I thought.
Berlin, Frankfurt on Main, (many/most cities in Germany). Actually, most of the large cities in Europe, notably London. NY, DC, Chicago. Portland is getting close and Seattle (if they keep their build rates up) should have it in another decade. I got around really well in Boston and Toronto with just the metro/tram/bus systems.
Tokyo’s trains are phenomenal, as are most major cities in Japan.
I’m sure that people would pitch in cities in China (I don’t know much about them). There’s plenty of places that have well integrated, city-wide, endemic transit systems that get you everywhere without a car.
