Self-driving Google carAnyone driving the curves between San Francisco and Los Angeles may have recently seen a small car with a curious cylinder on the roof holding video cameras, radar sensors and a laser device to “see” other vehicles. It was harder to notice that the person at the wheel was not actually driving. The car is a project of Google, which has been working in plain view on vehicles that can drive themselves, mimicking the decisions made by a human driver. With someone behind the wheel to take control if something goes wrong, seven test cars have driven 225,000 kilometres with only two human interventions. It drives at the speed limit, which it knows because the limit for every road is included in its database, and it stops for lights and stop signs.
Robot cars react faster than humans, have 360-degree perception and do not get distracted, sleepy or intoxicated, which saves lives and avoids injuries, the engineers argue. They also say that this technology could double the capacity of roads by allowing cars to drive more safely while closer together. Because the robot cars would eventually be less likely to crash, they could be built lighter, reducing fuel consumption. But of course, to be truly safer, the cars must be far more reliable than today’s personal computers, which crash occasionally.
The Google research programme, using artificial intelligence to revolutionise the automobile, is proof that the company’s ambitions reach beyond the search engine business. Autonomous cars are years from mass production, but technologists, who have long dreamed of them, believe that they can transform society as profoundly as the Internet has.
