Ten months ago, Apple proudly announced nine partners that were signed up to integrate Apple's Siri personal assistant into their cars. BMW, Mercedes, GM, Land Rover, Jaguar, Audi, Toyota, Chrysler, and Honda logos were all projected onto Apple's WWDC screen, with the promise that Siri-integrated cars would be coming within a year. But where are all of those cars? A few models have arrived, but the vast majority of the companies named last year refuse to detail if and when Apple-friendly models will arrive. Why? As Wired reveals, models set for release in 2014 were designed up to five years ago. Infotainment systems are planned years before a vehicle is launched, and typically won't be upgraded. So more Siri-integrated cars are likely coming, but don't hold your breath for an imminent release.
