text: The next diadvantege would be if someone had hacked into the the cars mainframe. If someone was able to hack into the car without the driver or owner knowing it can be very dangerous. It can be dangerous because they can track where that person is at alll times. They could tell if they're home or not and the owner can possibly end being robbed. Another way it would be dangerous is that the person that had hacked the car could control the car and may end up hurting the driver or people around the car.
