> the impact of air density on aerodynamic drag, which should be negligible at such low speeds The impact air density on aerodynamic drag is huge even in human athletic events - on the order of 1% or more [1]. The impact increases quadratically with speed so it should be 3-5 times more significant in the final stretch of a 0-60 than at the 25mph speed of a sprinter.
