In a sense we're already there. I use my Android to stream music, run GPS and display car diagnostics while driving (via bluetooth in OBDII port). I put in a fairly good stereo headunit not too long ago only to be disappointed that the majority of its software is tuned for Apple devices. I've already seen DIY articles on mounting tablet's in-dash and hooking them to the existing car sound system so having a plug and play interface for cars and tablets wouldn't be a difficult task for someone experienced in such fabrications. Hell, having 3D printers so prevalent now will speed this up even more. After all, a lot of the challenges car manufacturers need to overcome in the car computing world have already been solved by the likes of Apple and Google. Voice command, music, navigation, camera support, bluetooth, phone calls/SMS... its all already solved. Having a device that can then interface to an existing ecosystem just makes it even more appealing to the buyers who are able to be swayed simply for the gadgets.
