There are quite a few scenarios with a driverless car which I wonder how they will respond. How will it know when you are waiting to come out a side road and a kind person flashes their lights to let you out? If you are on a narrow road with very limited passing places and the person coming towards you flashes their lights to allow you to pass as they have pulled in ? If you are on a narrow road with cyclists in front of you how will it know when to overtake them? A machine cannot make choices to help other road users by being helpful. Human interaction when driving cannot be replaced by a machine and I think there will be problems in the future as more of these become main stream vehicles.
What are your thoughts?
