When you can’t get what you want, you teach yourself to want what you can get and then preach to everyone else that they should want it too. This applies to many other things too beyond just cars.
It’s not that the criticism of private cars isn’t valid, but not having one because you can’t afford it isn’t virtuous. It’s only virtuous when you could easily have one but choose not to.
No offense, but it’s telling that you didn’t post this in any of the anti-car communities…
Obviously, this heavily depends on where you live (I’m assuming the UK based on your username). In the US, for instance, it’s almost necessary to have a vehicle in most places. Our public transit is seriously terrible and underfunded, and passenger trains are almost non-existent.
This isn’t anti-car post and thus doesn’t belong in those communities.
