That's only for a 100% efficient system with no friction.
To get a vehicle such as my suburban up a hill, I calculated at a speed of 100fps, I think that was about 70mph a 4% grade doubles the amount of horsepower needed to maintain speed.
Unfortunately interstate commerce isn't as efficient as an elevator.
Soon electric hybrid tractor trailers may become common and I think they are going to have really big packs
Even then I really only expect to see them mostly in the city.
