And just yesterday the emperor issued a decree mandating higher fuel efficiency standards for heavy trucks. (you know, the ones that bring food to the stores)
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....
One area that does not need dear reader fiddeling with is heavy trucks. If say mack trucks came out with tractors that got even 1 mpg better than all the rest. That is what would sell the best. It makes $ for the operator. The other issue is the number one way they get better mpg out of a car is to shed weight. That won’t work as tractor trailer trucks are always loaded to capacity to maximize profit.
Good luck big truck makers.. your gonna need it.
