Because nobody knows about these, a “developed” country won’t “humble” itself with buying things designed for underdeveloped regions, cities are designed around cars, car manufacturing is still a major backbone to most western industries and politics won’t risk jobs by providing alternatives, it’s “unamerican”, leftist propaganda and queer, etc. In short politics is not rational, because humans are not rational. And that is neither good nor bad, it’s how humans work. To sell them these ideas you must make people excited for these changes and we are pretty fucking far from getting people excited about changing for a better, greener society.
