i did 180 in my NA, going down federal one night. was sitting at about 6.5k on the RPM. i figured 180 is fast enough (plus i ran into the car i let pass me about 5 mins before)
I have had this twice, no BS doing 40k and the loppy pop man goes beserk because it looks fast, one almost mounted my bonnet.
Same, this has happened to me a few times too. They give you this real dirty look even though I'm usually just under 40.
