OnStar is letting its customers know about changes to its privacy policy likely to upset many of the GPS and emergency response company's six million customers.

No, we can't afford a 2012 Lamborghini Aventador, and that's a crying shame, because we'd sure love to own one. If you're a gearhead, you'll appreciate this new model Lambo for its 691-horsepower V12 engine and carbon fiber monocoque. We dig those too, but the techheads that we are, we also appreciate the Tegra-inspired MMI infotainment system.

Chevy has something new in store for its 2012 Volt and Equinox models this fall. It's called MyLink, which you can think of as a smartphone on wheels. Building on the safety and security of OnStar, MyLink is a smart interface design that drivers can use to tap into mobile communications technology, all the while keeping their smartphones safely tucked away. Features like Pandora, Sticher SmartRadio, hands-free voice, and touchscreen controls are part of the package.

Tesla Motors CEO Elon Musk isn't buying into the theory that the world will end in 2012. How do we know that? Because the ambitious CEO is making some bold predictions for the next two decades.

According to Musk, long range vehicle battery backs will be ultra affordable by 2020, and if you find that hard to believe, get this. By 2030, Musk predicts that all cars sold in America will be electric, egmCarTech.com reports.

Musk's time-frame might be overly optimistic, but it's understandable given his company's desire to push electric vehicles. Tesla plans to unveil the Model X SUV later this year, which will be followed by an affordable electric sedan priced around $30,000.
