I’m not sure if it’s going to be a better world for humans, but roads so crowded with wheels that I don’t want to leave my house sounds like an economy where a lot of wheels are being sold.
The wheels are being sold to humans sitting inside their houses who have been told that if they have enough wheels on the road, they will make the world more productive. Meanwhile, the wheelmaker loses money on every wheel but gets money from the rubber factory. And the rubber factory gets money by selling its stock to the humans sitting inside their houses.
