I'm actually rather impressed by the carbon fibre-reinforced plastic. It did seem to hold up rather well. That pole test is evil, plain evil...but I think it goes to the lack of space between driver and the exterior of the door - it is a rather compact car. The Scion iQ doesn't do much better, nor did the Smart. It's something to work on - Subaru has to as well.
Whiplash protection is an easy fix. Overall, I don't think this is all that negative.
