Funny kill switch story.
Mine's mounted on the shifter so I activate it with my thumb. But I've hit it a couple of times with my knee on the highway and scared the whee out of myself. (The engine only stuttered briefly, but still.)

I think that guideline has been busted. There are more than a few production cars out there with efficiency-minded air dams that hang much lower than the lowest underbody components. See the Chevrolet Volt for example.
Another EG: I put a fairly deep airdam on a 2014 Mitsu Mirage and saw a ~4% improvement at just @ 90 km/h / 56 mph.
