I couldn't imagine my vehicle doing anything I didn't tell it to do, or at least do anything I didn't optionally allow it to do for me.

Maintain a certain distance from another car when I set the cruise control? Sure, that's not a bad feature.

Play a nasty little ad on a touchscreen "infotainment system" that is downright distracting to use as it is, especially when driving? That sounds like disaster waiting to happen.
