To be completely honest i feel it is fairly stupid to call the cause on the car itself and not look at the bigger picture. IMO the Indy Racing League should not be racing on cars like Las Vegas, Charlotte, Texas, Fontana or Michigan simply due to the speeds. The overall safety of the cars isnt what needs renovating, Indy just needs to be run on slower tracks (Think Milwaukee or PIR) in general. I for one woulnt mind seeing the IRL become more of a F1 sort of series, only running road courses, with the Indy 00 being the only exception.
