text: The first of the many problems is the road problems that can hurt any one on the road. If there is a sewer problem in the middle of the street that the city workers are working on the driverless cars won't have a way to detect the workers. Yes they might install a camera or a sensor to indicate that and alert the driver, but it can alert him to late and the result on that is there is already a crash. Also the car can't tell whether their is a red light or a green light it can only go to the direction it was programed to go to. There can be many more problems that anyone else can say that I'm not saying and think to your self's "why do they need to alert you before the car doesn't know how to drive a certain way".
