That was a good movie. But not what I had in mind. Something involving contract hit men who use this technology to kill people for hire while leaving no trace.
They could enhance the plot by giving the technology the ability to lock all the doors and windows, filling the interior of the car with carbon monoxide and tweeting suicide notes from the onboard social media interface. Oops, now this will be designed in the black box that the government will control on 2014 models and later.
