I agree 100%.....Those cars are just jet wings on wheels and once a front tire looses contact with the pavement, they go airborn
IMO, putting 34 cars on a high-banked 1.5-miler is just asking for it. With a smaller field (and maybe fewer rookie drivers) they might have been okay there.
But myself, I prefer watching them run on flat ovals; those require the driver to do something besides stand on the throttle.
There were at least 2 cars that went airborne on the clip I saw. Seems like the open wheel cars have a propensity to leave the ground if they rear end another one. It happens in F1 also..
