The example was just to illustrate the savings potential from drag reduction.
Here's there drag table from the experiment,shared by member jalmir,which I added a delta-Cd table to

If the Mythbusters car had Cd 0.35 for instance,at 2-feet clearance,it's drag would be the equivalent of Cd 0.077.
And the Chrysler engine reacted favorably.
If one were to momentarily approach an 18-wheeler and check the instant MPG readout,they'd know instantly,the absolute MPG maximum possible from streamlining.
Then one could act accordingly.
