Your First Car Could Drive Itself!

Forget adaptive cruise control and parking assist, by 2020 you could have a completely self-driving car.

Prototypes from Nissan, Volvo, Audi and Google use a variety of sensors mounted on the cars to produce a detailed picture of their surroundings. One of the main sensors they use is a type of laser that sends out rapid pulses of non-visible light and measures the time they take to bounce off objects and return. Because light moves at a constant speed, the car’s distance from that object can be calculated and used to build a 3D image of its environment.

The data from this laser is also combined with video and radar sensor information picked up by the car, and is processed by a self-learning, onboard computer that decides when to steer, break, and accelerate.

Which all sounds pretty good, and benefits of this technology have already been identified, such as giving mobility to those who can’t drive traditional cars, and removing the risk of human error, which is the cause of 90 percent of traffic accidents in Australia. But what are the risks?
