It is a start in design change and I am sure John studied it very closely. It was done several years ago. The way I see it was test #1 was a success. Test #2 with an already compromised frame and the extra Mass of the sled was just a way to finish the poor car off. More testing needs to be done, however testing is very very expensive. Possibly just studying other crashes more closely would be of great benefit. Have you ever noticed that the majority of driver mortality usually occurs in very mundane and ordinary looking crashes while the spectacular crash only show up in a movie and is titled "And they Walked Away"??
Probably the biggest safety improvement for the racer in years has been the "safer barrier wall" It can lay it roots back to Indiana, Rose Hulman Institute of Technology, and Tony George. It started out as a simple university experiment and study and went on to become something great for racing.
