Do self-driving cars really prevent accidents from occurring on the road? Most people would think they would due to the multiple technological advances such as the 360-degree sensors or the self-parking feature. But according to a study done by the Insurance Institute for Highway Safety (IIHS), autonomous vehicles are not the answer to eliminating vehicular accidents. The IIHS examined 5,000 crashes and determined that self-driving cars are only capable of preventing one third of automobile accidents. The Institute found certain driving mistakes such as misjudging speeds of other vehicles or high speeds on dangerous roads cannot be prevented from the current state of autonomous vehicles.
