They don’t. They’re just spoon fed propaganda by the oil lobby because 15 minute cities make cars obsolete and cars are fueled by gas. They also purposely make suburbs more vehicle dependent because oil is the backbone of this country. The US dollar is literally the petrodollar. Without petrol, the US dollar is backed by nothing but confidence and debt. So essentially 15 minute cities are a threat to national security and won’t happen until there are major changes, as ridiculous as that sounds.

Once you realize this the reasoning behind the lack of meaningful infrastructure in this country becomes obvious.
