Totally agree with the second sentence, but disagree with the first. It's not like these features are just thrown in for fun; there is research and testing behind them, and they do save lives.

It's like that oft-misquoted statistic that you lose 50% of your body heat through your head. In reality that's only true if you cover the rest of your body with clothes, but leave your head bare. Obviously wearing clothes is going to keep you warmer than wearing a hat. But, if it's cold out, it does make sense to put a hat on too.
