text: The danger that everyone's life is in around a driverless car is serious. A car cant sense everything, just think if a pedestrian was crossing the street from behind and the car didnt sense him, the pedestrian would be hurt. If a emergency vehicle is coming, flying down the street and the driver is not alerted fast enough the car could do the wrong thing and get hit by the emergency vehicle and everyone in the car could be seriously hurt. This could all be avoived by cars having alerted drivers at all times.
