with cars that push 300mph, and that cover a lot of ground at higher speeds, I have to wonder.
i.e. you cannot ignore that big blue plume of low pressure behind the car without considering a boat tail, that low pressure is acting on the rear of the vehicle and is going to be pulling the car back for a large part of the track, exponential with speed.
