Very interesting reading reading, particularly the one on the aerospaceweb. In the case ov the car which is not rotating do you not think that it would only be necessary to put the dimples in say the last third of the vehicle? Or perhaps some simpler way of creating turbulance, as on the Gloster Javelin.
Golf ball that does not rotate creates even less drag...called a flyer.
I once had a 250 m ( 288 yards ) stroke with an i5 ( 10 years ago ).
