Reason being well, I use them everyday. And they are not sufficiently developed here. I have to walk 20 mins to get to a slow ass shaking train.
Metros I like but stops are far away both to my home and my job. Couple that with the overpopulation and crowdedness it makes a very consuming and tiring experience. Not fun at all when you ride half an hour ass to ass with another person. Especially when you are an introvert.
Busses? I avoid them as much as possible. It is slow, shaky, even less space and more people than metros and trains. I love getting stuck in traffic with strangers breathing in my face.
This is understandable in the current neoliberal age of udnerfunded public transportation.
In my country’s case the tramway tracks were removed in the 60’s to make more place for cars (freedom baby) and the train network shut down a decade or so later. A few years ago the public bus service also went broke, after intentional underfunding and many (failed) attempts to privatize it. Now we are left with a few companies and businessmen maintaining a monopoly over bus transportation which doesn’t even cover all the areas.
Incidentally, roads and highways are still being expanded because there can never be enough to house the ever-increasing car population.
