Because it has to be repeated again and again: We need to drastically reduce the number of cars to solve our problems.
Our Western automobile-focused culture is unsustainable on a planetary scale. The global ecosystem would collapse if all people owned and used cars like we in the West do.
Any statements regarding "most people" or "all people" should take that into account.
Major branches of ethics require you to make exactly such statements. (Read Kant, for example.)
