Hit 100 going downhill with wind at my back - tying to make sure they fixed the seal leak/whistle in my windshield replacement (on my fifth windshield - gotta love living in CO) - anyway, back to the point - no whistle at 100, even with the gust of a semi coming the other direction....
Around 80-85 mph once.
I used to roadrace and dragrace motorcycles, I filled my "need for speed" long ago.
Now I'm that old guy plodding along at the posted speed.
