I think there's a good chance it could. The cells in the pack might have prevented it from deforming, which could have prevented the puncture. Or not. In any case, if this is an uncommon, but consistent problem, I imagine that Tesla will come up with something to better secure the pack.
It may or may not be. But ultimately, if this isn't a freak accident, and is just uncommon (say one car per year), it's probably worthwhile for Tesla to change their module design.
I strongly disagree with this as a factual statement. We don't know enough to say whether or not this is a freak accident. If an NHTSB investigator has already compiled a report on this accident, and also happens to have a readily available database of objects that have been involved in other accidents to compare to this object, then they could state whether or not this is a freak accident. But all the rest of us can do is speculate. Barring that, only time will tell.
Prior to this thread, none of my posts expressed doubt, and even in this case all I'm asserting, as I've said before, is that the car may benefit from an improved module design if this isn't a freak accident. No car is perfect, and that includes the S.
