text: The car is also very easy to take control of. For the things the sensors can not sense the car will alert the driver when they need to take control. The human in the car should always remain alert for when these problems may occur but if they can not the car will send the driver an alert. The new driveless cars will have seats that vibrate when the vehicle is in danger. If the driver has fallen asleep then the vibration of the car should be firm enough to wake them up. Now while the driver is just waking up they do not really know what is going on, so the driveless car will also announce that there is a problem and the driver should take control. By the car announce when there is a problem is very helpful because if one of the sensors were to go out then that would be a problem and the car will announce it and the human will take over.
