This is ultimately the thing that needs to be fixed. The exemption for small trucks was stupid, and it should have been reserved for literal farm equipment (as that was intended). The fact that SUVs slip by on this now has created such a dumb market.
The OBBB Act passed by Congress last year eliminated the financial penalties associated with violations of CAFE standards, so there’s presumably no reason why automakers have to abide by them anymore, except possibly for concerns about future legislation.
