Even the summary gives some context to this, which is that it's about lowering fuel emissions standards in the supposed belief that this will somehow make small cars legal (uh, what?) So, it's still dumb.
And I'm not praising Trump for some slightly positive thing he might have said any more than I'm going to praise a certain German dictator of the 1930s for building an interstate highway system, improving the trains, and starting a company to make small affordable wagons for the volks.
Look, in the end, we know what Trump's doing. It's a grift. It's not even a smart, well hidden, one by a smart person, it's just dumb shit that takes advantage of marks who'll buy anything. Trump accepts bribes, he sells things with his name on it at ridiculous prices, he's in it for one thing only. In the meantime he hides, as his ilk always does, his gross incompetence by pointing a finger at minorities with no power, claiming they're responsible for everything wrong, and making public displays of "cracking down" on them, where the cracking down is intentionally cruel and rotten so nobody can claim he isn't "doing anything".
So he promoted small cars? So what? You think he's doing that because he cares about global warming or intracity congestion or sky high car prices? You think that him promoting them will in any way make America a better place, even if that's not the intent?
