The point I am trying to make is, of course, the relative efficiency of large vehicles varies much more with load than it does in smaller vehicles.

I dispute your disputation. ;-) I saw a Scientific American article about transportation a few years ago, and Jet transports are much more efficient than any gas powered ground vehicles because they can move such enormous amounts of cargo. Of course, ships are not counted here, which are even better.

I was a bit puzzled by your comment about jumbo jets. They are actually pretty efficient even though they use a lot of fuel because they move so much stuff. They are certainly more efficient than
trucks.
The problem is they have to land at airports, whereas trucks can go anywhere.
I think that the problem with airliners, other than the fact that they're not very fuel efficient (I dispute your comment wrt jets being more efficient than trucks), is that jets add significantly to the cloud and haze cover, and hence are accelerating greenhouse effect.
That is, if you believe in the greenhouse effect, which I know that some here don't.
