I knew what this was before I even looked at this movie, I was watching this event on TV when it happened.
It'd be interesting to see how this car performed in wind tunnel testing, if it got "light" as speed increased to begin with. I think in general, a lighter vehicle must be smaller to obtain a density such that it won't be subject to the wind gusts, pressure waves from passing vehicles, etc. Many of these lightweight race cars that are very wide and low, create a near perfect shape of a wing and coming over a little knoll with a headwind is all it takes.
The amazing part was the driver walked away from that IIRC...
On a different subject, I found a local place near work that makes fiberglass bathtubs and shower stalls using the chopper gun sprayed fiberglass. While it's not optimum, I could certainly have them spray their stuff into a mold taken off of the aluminum bodywork to save some weight and make parts reproducable.
