text: Finally, my third reason why I believe that driveless cars should not be developed is that if the driver is not taking caution they could cause harm to other people. If the driver sleeping and not paying attention to the road even though it is a driveless car it could cause harm to the driver and other people. Since the driveless cars are not fully developed the driver has to make sure that they are staying alert. Even though it might have a sensor in the car what if it sensor fails then how will the driver be alert that a traffic situation is ahead. Right now the traffic laws say the only safe car has a human driver in control at all times. Also driveless cars are illegal in most states and its also illegal even to test computer driven cars.
