i agree with everyone saying the parkway is a quick crowd for the most part. 10 over is pretty acceptable.
lets look at it this way shall we.
85 in a 55 is 30 over.
lets compare that to a 25 zone.
55/85 = 25/X
cross multiply
85x25=2125
55xX=2125
divide to find X
2125/55=38.63
X=39 rounded
so 85 in a 55 is equivalent to almost 40 in a 25!!!!! that is quite fast. sure there are a bunch of other factors and all that jazz but i was bored and felt like some math.
i have ridden in vinnie's car and he is a good driver, car sounds awesome with a cut out, and i'm pretty crappy at directions
