Automakers are creating vehicles intended to serve as mobile offices, with built-in media hubs, Wi-Fi and other business-focused gadgets. The 2013 Bentley Mulsanne includes built-in video conferencing tools, drop-down iPad stations and a champagne chiller to help CEOs celebrate success. "People, when they're in the back of this car, they like to do business. ... They're not desperately interested in the scenery going by," says Kevin Rose of Bentley Worldwide.
