Flip side of this is that every one of these regulatory rollbacks will get challenged in court as arbitrary and capricious (after all, no more Chevron), reinstated by the next Democratic administration anyway, and possibly not even be functionally repealed (creating potential liability down the road), so at least for a while manufacturers will probably continue to act as if the standards are still in effect.

This, of course, is exactly the kind of chaos and uncertainty that the APA and all those agency processes are supposed to prevent, but it’s a roller coaster for the next few years at least.
