” pick up an audio accelerator blip from a car closer to the stands.”
Yes! Much more likely it was a car on the front straight, where the vid was taken from. Even at caution speeds, these guys have to “blip” the pedal, or the engines are likely to flood and stall. Remember, no transmission, no gears, a direct hookup to the rear axle, with only a clutch in between. Clutch it, blip it, then back into direct gear.
NASCAR Legend Tony Stewart ran into and killed an angry, stupid, sprint car driver on the track while doing 35mph under caution. I guess that pretty much sums it up for me.
My video camera is specifically designed to reach out and grab audio from where it is pointed. Its smart sound.
