That is a variable this is not considered in this test. That is also the reason why no test can replicate 100% real world situations.
U can have an accident in a top scoring car & get killed, yet it's also perfectly possible that u survive without a scratch crashing in a deathtrap.
As for the Volvo, an explanation as to why they have this feature is cos there are lots of accidents involving hitting wild animals in Sweden. The way a UK member here hit a deer in his brand new F30 reminded me of this.
