I am pretty anti-car myself, but the last point of the post makes me think that the author hasn't seen how personal transportation plays in ENORMOUS role in the everyday lives of families who live outside of major cities in the US. I'm a young 20-something pursuing a career in tech, so I'm part of the demographic who is most able to avoid car ownership.
I went to school in the south, and got to see firsthand how many of the thousands of people who worked for my university were only able to get to their jobs because they owned a car. My school, like many others in the US (Virginia Tech, UIUC, UPenn, etc.) was out in the middle of nowhere, and was by far the largest employer in the county (and surrounding counties). My school subsidized a fleet of several buses to make public transportation feasible, but those bus routes often were 5-10X slower than personal transportation and were undersupplied and undermaintained, making it difficult to use them as true replacements to car.
