A requirement than can be almost instantly met by half-loading the rigs. Price per item shipped will necessarily skyrocket. I'm starting to detect a pattern here....
Freight hauling is already finely balanced between fuel efficiency and cost effectiveness. You can’t increase one without causing the other to suffer. Government stepping in and demanding higher fuel standards will cause cost effectiveness to suffer and drive consumer prices up.
Trains are incredibly fuel inefficient if you assume they’re running around empty all the time. However if you look at the amount of freight they carry against the fuel they use they become very efficient freight haulers. (Something like 400 miles per gallon per ton)
BUT! BUT! BUT! It’s not fair (queue up the tears and violins) that people in other(African) countries spend so much more of their income for food than Americans do.
As we all know “White folks greed leaves a world in need”.
That jug eared clown told everyone he was going to drive up the cost of food but people didn’t listen or worse they just didn’t want to hear.
