Dear god, the level of conservative whining on here is unbelievable! We're talking about an innovative vehicle here. You complain about your own safety but does anybody ever think about the safety of others? Less weight means you won't kill other people. Fuel efficiency means you cause less suffering to your grandchildren who will suffer from the dramatic climate change. This is a great change and you all act like Hitler rose from the dead. I mean, what is wrong with you? Airplanes are made from aluminum and I don't hear the whining and crying about that. Worse still, why are conservatives so dang predictable? What a freakin surprise that you're all upset about innovation on four wheels. Nobody is surprised.
