text: My second reason for why i do not support this technology is because so far the cars are not that efficient. Yes they have all these sensors and in normal circumstances work perfectly fine, but when there is any situation on the road the human driver must take over. These cars are also set up so the human driver has to almost just as alert as they would be in normal car. If the human has to be just as alert and may very well need to take over if the road or traffic conditiions are out of the ordinary, what is the point of having a self-driving car? Even if they could work it out so that the car is one-hundred percent efficient on its own, it would take quite a bit of money for that technology and as simple as driving is i do not find it to be worth the effort.
