I have noticed that our percetion of speed changes if we are watching the car go around the track vs. actually driving the car. For me the car seems slower while I am driving than when I am spectating. Keep this in mind when you are driving as speeds can be decptive when changing perspective. In other words, trying to copy someone elses "percieved speed" while watching can get you going too fast to make your car handle correctly.
I hope I said that right. LOL
