RIP Dan Wheldon

Another consideration is that a number of these cars hit the catch fencing, which is going to rip a car apart regardless of its construction. Especially at 200+ mph. If an F1 car or even a stock car would hit the fencing at that speed it would be a similar result.

Take a look at Robert Kubica's crash in Montreal back in 2007. The car hit an exposed wall and disintigrated, much like the indy cars. The only difference being that he just hit a wall and not the fence, which would have ripped his car to shreds.
