QuoteOver all those are very good numbers, I don't question the accuracy but a couple things to note, first what was the cargo weight moved? they give the gross weight, I would like to know the cargo weight. Also they have achieved that with a 80 km average speed. That will help keep wind resistance down. In Alberta Currently the hyways speeds are 110 to 120kmhr. Doing 80km would risk you being run over or off the road.

For 13 years (January 1974–April 1987]), federal law withheld Federal highway trust funds to states that had speed limits above 55 mph (89 km/h).

During World War II, the U.S. Office of Defense Transportation established a national 35 mph "Victory Speed Limit" (also known as "War Speed") to conserve gasoline and rubber for the American war effort.

It will be a long war or a 'long emergency'.  I vote for the long war.  The speed limit in 2045 could match the speed limit of 1945.  I prefer that over the long emergency libertarian nightmare of:

      35 and alive or 80 and Fred is dead.  I do not see this as a hard choice.  I too would like to know what 'fully loaded' means.  Popcorn?  I want the kilograms.

First technology must be able to  get the job done.  Then it has to be implemented the right way.
