Cars are fine if you use them appropriately. They're great for trips from one city to another (> 10 miles or so) or if you need to carry something really heavy.

Cars are fine if you use them appropriately. They're great for trips from one city to another (> 10 miles or so) or if you need to carry something really heavy. Otherwise walking, biking, or public transportation are preferable. If your life is arranged such that all the places you commonly need to go are > 10 miles apart from each other, consider changing that.
