Personally, I think that autopilot is a bad idea. Being engaged while driving is important to our survival or at least to maintain our skills.
Can you imagine having an autopilot in a chess game where it only depends upon you to make the most critical decisions? The player would not be fully engaged.
Maybe in a decade, it will be perfect. Maybe the computer will be safer than my own driving, especially as I get older. I can see using the time for something more productive.
