Here's one from the how'd-they-figure-that-out file. It seems a number of Mazda 3 owners in Canada have reported being victims of a super-secret way to get into their cars. Apparently, if you put a large enough dent in the side of a Mazda3, it unlatches the door and fools the computer into thinking the entry's legit. Thus, sledgehammer-wielding thieves have been relieving car owners of their possessions with relative ease. According to a Mazda source, the company's known about the problem since last October, and is working up countermeasures. In the meantime, don't believe that guy in a leopard loincloth and handlebar mustache lurking around the parking lot with a giant mallet. He may be up to no good. [Thanks to R. for the tip.]
