I have to agree. Most people I know would rather take a bus to get to work, for example, but don't because it would require significant walking, more time, and restrictions on when you can travel. In my case, for example, if I take the bus, I have to walk 1.5 miles to the bus stop (in temperatures ranging from -20 to 100), then ride two buses for nearly an hour. On top of that, I have to hope I don't miss it, because it only runs once per hour. Or, I can drive and go whenever I want and get there in 15 minutes. Hmm, tough choice.
Public transportation is great until you have to make multiple stops, go to the grocerey store and get large/bulky items or a lot, or have a family and/or young children.
I've spoken with several friends who have young children and it's just too much effort to coordinate the transportation and the children at the same time.
Obviously some people have no choice - but given a choice I think anyone with young children prefers a car under most circumstances.
