It's odd to compare the drag of a truck with huge frontal cross-section and zero downforce with that of a supercar that has a tiny cross section but large drag coefficient to create downforce. An F1 car would have an even higher coefficient of 1.0...
Compare it to a normal car instead, and it's the equivalent of an old Chevy Tahoe and far worse than normal saloon cars which are typically at 0.29ish.
"The Tesla Semi’s drag coefficient of 0.36 is lower than today’s trucks at 0.65 to 0.7, and even lower than the Bugatti Chiron at 0.38, one of the world’s fastest sports cars" [1].
Objects with good drag coefficients are usually good looking, or are not hard to make good looking (while not so true for the other way around).
