I understand that some governments have penalized car ownership by way of license plate restrictions and other tax situations (I've heard that license plates in China get auctioned for $12k USD because they're so rare). This turns owning a car into a vanity symbol for the wealthy. It may not even be an intentional symbol, but I'm sure that's the way it's perceived by those who don't own a car.
My point being that for some, car ownership isn't so bad. No need to go shaming people.
