Changing minds on guns, cars, and red meat is exactly as easy as setting up and constantly reinforcing the original (toxic) narratives around guns, cars, red meat, sugar, and the rest.

It isn't difficult or expensive in its own terms. You don't do it with "public education", you do by consistently dramatising the results you want in popular media, and demonising the results you don't.

Give it ten years of consistent messaging from multiple seemingly independent sources and it's done. Give it twenty five and it's so done the alternatives are no longer thinkable.

The difficult and expensive part comes from the enclosed nature of political power in the US, which has a choke point on the kinds of messages that are allowed to appear in popular media.

Cool, now you just need to convince popular media to include narratives about better road design and use in a way that is subtle enough to avoid pushback but obvious enough to have the intended shaping effect. This sounds both incredibly difficult and incredibly expensive, but you say it's not, and we have no way to test which one of us is right. Agree to disagree. :)
