A driverless, or autonomous, car is a car that can operate and drive itself without the need for human interaction. Autonomous cars are able to navigate independently using systems such as GPS, radar and are able to sense the environment around the car using sensors. Many major automakers, including Ford, General Motors, Audi, BMW and Volvo, have begun testing autonomous car systems. General Motors predicts it could have a fully autonomous car on the roads as early as 2018[1]. There are many benefits to autonomous cars, such as fewer traffic accidents, reduced congestion, relieving occupants of navigation tasks so that they are free to do other things, and autonomous cars can be used by anyone, even if they have a disability such as blindness. There are also some disadvantages to autonomous cars, such as the risk of malware and hackers modifying the car's system, which is to blame if a car is involved in a collision, and bugs in the car's system. The main question about autonomous cars is: do we remove all human interaction from the car's controls or still let them retain some control in case the system malfunctions. One of the biggest advantages of autonomous cars is the reduction of collisions in traffic since the car is driven by a computer that uses sensors that detect obstacles and react to obstacles faster than any human can. If a car suddenly brakes in front of you, the computer will be able to react and slow down the car much faster than a human. Google tested eight self-driving cars, and each car posted perfect driving records. Only two accidents occurred during Google's testing of autonomous vehicles, and both accidents were caused by human interaction and not the fault of the car [2]. Google announced that its… paper vehicles… tonomes include fewer traffic collisions, less traffic congestion, the vehicle is capable of navigating independently, and anyone can drive the vehicle. There are also a number of disadvantages which include people hacking and modifying the car's computer system, which is to blame in case of collision in traffic and problems with bugs in the car's computer system. I believe that, eventually, it will be safe to eliminate all human control and have fully autonomous vehicles, but only after they have been thoroughly tested. Initially, I think that the human being should maintain some control of the vehicle in case something goes wrong, for example, if the car fails to brake at a red light. But once the systems have been thoroughly tested and people feel safe enough to sit in a vehicle without any control over it, autonomous cars are likely to become the norm in the future..
