How do you think people don’t already buy the cars they need with the money they have?
Because they don’t sell smaller cheaper cars here due to bad regulation. Most European/Asian cars look nothing like the big stupid SUVs here.
And that’s just not how economic externalities work. When you ignore them, these costs don’t just go away and make things “more affordable”. We all pay for it. In fact, costs falls especially on the poor, who disproportionally tend to use public transit instead of buying big shiny new trucks.
Of course I don’t mean that literally not a single small car is for sale. 🙄 Anyone who has done even the most cursory search knows that the market for small cars is extremely different in other parts of the world. When you’re misinterpreting my comments in such an uncharitable way, I don’t really see a point in continuing this discussion.
When did I ever say we should “double the cost of all vehicles”? What an insane way to argue with someone! You can’t just invent stupid positions and attribute them to your interlocutor.
I agree with your proposal. A road tax based on weight internalizes the externalities. It sounds like you think we disagree because you don’t know what an economic externality is. Instead of your glib reply, you could… look it up before replying.
