Worth nothing that those standards were begged, pleaded, demanded, cried and shitted for on the part of every major US automaker before they were passed, and it was only after that/because of that that every major automaker began working like hell to sell the American public on SUVs and trucks. Simple fact is that full-size trucks are the only vehicle category that Detroit is able to compete on (less so now than then, but then this was extremely true) after they got their asses roundly handed to them by the various Asian ones that did cars, vans, and MPVs much better.
US automakers bet the farm on building ever larger and more ridiculous vehicles for Americans because it was just easier than competing with the Japanese/Koreans on a fair field.
I hope like hell this goes somewhere and we can get these stupid things under control. Feels like every Tom, Dick, and Harry around where I live is driving a 3-ton or greater truck that's never seen anything more strenuous than getting a load of fertilizer for mom's garden, and like, that's fine. But their choices in vehicles are putting negative externalities all over the community and risking everyone's safety, including their own children, and it's fucking ridiculous.
