And then the people across town need to travel somehow, so they need a car, and then they're spending more on a car (lots more), and then they fill up the roads, and then we need to pay for more road infrastructure, and then we have more cars to replace with BEVs because we can't possibly continue having gas cars around.

Or we can try to get more housing near to where people work and get the things they need, and we avoid every single problem above.
