> Cars are fast, and in areas that are not ultra high-density, they save time relative to ANY alternative (walking, biking, buses, trains) and therefore drastically improve your quality of life

I mean, of course, does anyone deny that. They improve your life over the lives of others. Cars are incredibly bad for society, insanely bad. If someone had come up with the idea of a private car today, they would be rightly lambasted for their idiotic and dangerous idea. 2 tonne chunks of metal hurling down streets at 50mph mere feet away from unprotected people? Insane.
