rotors excite me

the '7 is pretty aerodynamic, so I imagine the flip ups play a fairly significant role at speed, and more so gradually the faster you go. if you had flip up lights on a Honda Element, I doubt it would make nearly as much difference. The stupid thing's already a rolling brick.

didnt they stop making flip-up lights cause it was hurting the people that got ran over by a car too much??? i mean wtf, i'm running you over with my car, i dont care how much pain your in

I know that. I meant at what point is it a significant term in the drag equation. If at 10 MPH it's 0.0001% of your drag and at 100 MPH it's 0.01% of your drag it's definitely insignificant. If the numbers are 1% and 30% however, that's a meaningful difference.
More precisely:
What is the total drivetrain drag on the vehicle?
What is the airspeed drag with the lights down at 30 mph? 60 mph? 90 mph? 120 mph?
What is the airspeed drag with the lights up at 30, 60, 90 and 120 mph?
Why do I keep starting to type "dragon" whenever I type "drag"?
Why do I do the same for "ration" and "ratio"?
Funny thing is, the most aerodynamic production vehicle (which was neither the Element nor the FD) looked like a rolling brick.
