What are these guys smoking?

I just saw this story on the BBC News site. Quote from Dieter Zetsche, chairman of the management board at Daimler and head of Mercedes Cars : "There are many studies that say it took 120 years to get to 800 million cars around the globe, and that it will take only another 30 years to double that volume," he says. "If that is true, the best is still ahead of us." Don't you just love the blind optimism: the faith? And of course, it's all good!
