This is not apathy in my opinion. This is rational. Cars are just tools. Metal boxes to enable mobility. Car people have turned them into this cult of personality that I think is batshit insane. It's not just cars mind you, we do this with watches, shoes, you name it and it's all very peculiar, but cars are my pet peeve because they are so obviously wasteful and dangerous. Not just directly like killing 40k per year in the US alone, but also through obvious geopolitics.
People want to move around and they want to smile smugly and think they are better than others. Those two things are pretty much universal. I say we separate those issues. You can move around all you want but smiling smugly you do in some other way than in your "car". We'll have really good public transport and you'll assert your dominance in some other fashion. I personally recommend we reintroduce dueling to the death.
By the way I don't know anybody that would buy a new car every two year to keep up with the Joneses and I live in a pretty "Jonesy" place. That's a bit hyperbolic at least in my neck of the woods (Netherlands). Most people here keep their cars until they become unreliable.
