I ran across this article on the blog of malwarebytes - it actually popped into my email as I have a subscription - about Ford filing a patent application for an IN VEHICLE eavesdropping system that will serve you targeted advertising. Blog post linked here:

I have to say - IF this system comes to Ford - I would never be interested in owning another one of their products ever again.
