Good god, can you imagine what Elon is thinking about when he's in a car? Me neither, but I'm sure it doesn't translate to good safe driving. For that matter probably very few of us have control over our thoughts enough to control the car's actions. Obviously we have some kind of brain to body filter that mostly prevents us from acting on our impulses - except giving the finger and stuff. I know I still have this stupid "pedestrian running across the road - worth 10 points" thing that goes through my head from grade school or something, I'm not sure why it's there, but I don't act on it, some part of the brain filters that out. I'm not sure if a mind-reading headset would do well. That would be a pretty lame defense in court "Sorry I didn't mean to run the red light, my brain told the car to do it".
