This is a willfully ignorant and wildly incorrect take. Your isolation argument completely neglects socialization with family and friends that is supported via automotive mobility. Do you also somehow have the impression that automobiles somehow forced suburbanization? I think not- you don't want others to have the freedom to choose anything other than some industrialized urban existence. The effects of the automobile are vast, subtle, and cultural- and overwhelmingly positive

I would be very surprised if you could show a study demonstrating increased use of automobiles improves socialization with family and friends.
