Insane people at Mercedes-Benz

When Daimler crawled into bed with Chrysler (only to slink out again a few years later) I remember wondering what they were thinking. Now we know. They’re nuts.
The latest evidence seems to be conclusive. In a much-run commercial for one of their new cars, an E-Class Coupe races through the woods somewhere near Stuttgart. Meanwhile, quick cuts show a car museum in a Bauhausy/Gehry-y kind of office building, isolated, like grandmother’s house, in this bucolic paradise. Inside, unsuspecting yippies and their urchins wander around oohing and aahing at great old Benzes.
Meanwhile, the new car races through the woods where there are, apparently, no police. The people inside the building hear it coming and barely get out of the way as the lunatic driving the damned thing smashes it through a glass wall and, somehow, pulls a 180 stop without totaling the new coupe, the old cars or any of the people he barely missed.
What? The brakes failed?
