The skirted trailers don’t save a lot of fuel, but they do save some.
Let’s say they save 1 gallon of fuel for every 500 miles a truck drives,
Let’s say there are 1 million trucks on the road doing 500 miles a day,
That’s 1 million gallons of fuel a day being saved, not polluting our air.

Being behind the bus, or the movie?
I liked the movie, I like other disaster parodies as well.
And don’t call me Shirley.

Speaking of Big Rigs, I noticed the 1970’s tv show “Moving On” is back on the air in re-runs on one of the broadcast tv stations here. It’s about two partners who co-drive their own Big Rig from one end of the USA to the other, hauling stuff. Mostly filmed on location, wherever they happen to be at the time. It seems to be replacing Las-Vegas Danny’s “Counting Cars”, hopefully this is just a summer replacement. I did quite like that show when it was originally broadcast. Teenage me made a point to watch it every week, but it may be too much of a soap opera to hold my interest now.
The sticking point is that you can nor design a aero trailer without compromising the weight capacity, volume capacity, loadability, or length ( controlled by law ) o the trailer.
