Who even considered entertaining the CAFE standards? They are completely unsustainable and unrealistic. As for the body design of vehicles, glass is actually the heaviest component for it's total surface area which explains why most cars now have small windows. The US standard safety testing methods are hell sketchy too. Cabin crush test? You planning on an elephant (or that morbidly obese Karen...) sitting on your car in the carpark at Walmart ? If the cab is going to deform, it'll be barrel rolling at 80 on a freeway and not a lot survives that in the best of conditions.

As for EV's - it's simply impractical to plan a long distance trip dictated by where you can recharge and waiting that long to get back onto the road. They do not like cold weather conditions either, and efficiency suffers in those conditions where the last thing you want to happen is being stranded out in nowhere. You want to be able to at least stay warm but can't risk discharging the battery out of fear. Just...no.
