Who has the liability when some one breaks in and puts bad code on the car that causes it to misbehave? The code could maybe cause it to not properly brake and cause a death or it could maybe alter the timings on the injectors and cause it to be less efficient or maybe even ware out more quickly. There has to be a certain allure to having a wifi chip in there and when you pull in to your garage at night, the car could install any updates to the ECU, the navi and any other systems that could need them, maybe sync against your itunes.. At the same time, it could send in some information about how it's performing, what maintenance has been done, etc.. It could almost be a profitable feature.
