I will say their tests were impressive. However, at least with the first frontal test, there was sure a lot of popping with the CF frame at, and before 1400 lbs (failure for Al). Perhaps the idea was to simulate a single brief impact, rather than holding it with a continuous extremely high pressure, however, it might have failed at a lower pressure if the compression had been slower, or there had been repeated high pressures.

Certainly it shows some advantage of flex with the CF over aluminum rigidity.
