This is in SolidWorks, no? Perhaps I'll have to talk to some product design students to see if we can't figure out a Cd feature or something.

For reference: 60mph/100kph = 88 feet/sec and 27m/s.

So, driving a relatively safe 2 car lengths back, the car should be positioned about 175 feet or 54m back from the rear of the semi. 80m would be about 3 seconds.

If the airflow coloring is different at the car than it is going over the semi we should see some improvement, right?
