text: Everything has it's pros and cons but in this situation there are more cons than pros. With a car that has a mind of its own you can never be too careful when it comes to your safety and well being and making sure you and everyone around you will be safe. First of all the cars will drive on their own and that might make you very tired and cause you to start to fall asleep, but the cars haven't been able yo drive through road damage, wrecks and there are alot of those everywhere and if your asleep you cant assist your car through the damage.
