I agree with z-man. In an f-car, I don't want nav and all sorts of crap. A stereo, yes, but really nothing else. That's a car you drive to enjoy driving - why would you want distractions? I would hope as a safety precaution Siri is automatically turned off under heavy acceleration, hard cornering and high speeds.

Now if this were offered in a lexus or similar, I'd be very interested.
