Re: Driver in charge?
People when sitting for hours doing nothing, as was this safety passenger (NOT a driver), become bored and disengaged from their surroundings. Add to that the fact that the passenger is not directly involved in driving, so that when they see something ahead that could possibly go wrong there is a tendency to wait a moment or two to see if the car is going to correct itself; a delay that could very easily leave it too late to change the situation. This, apparently, is what humans do. All of us. Having a human safety passenger is deceptively comforting. In a real emergency they are very likely to fail, as did this cars systems.
