"But have you ever driven somewhere you've never been before, and your GPS said, in 500 feet, turn right? And you look to the right, and it just doesn't seem like you should go that way, because the road is dark, or there might not be a sign, and everything in you says, keep going straight, but the GPS is saying, turn right. So you have a decision to make. Do you trust the system that can see what you cannot see, or do you trust your own eyes and senses and keep driving the way that feels comfortable or familiar?"
