She complies with the code motorists no: crashes the Google car – The Republic

ADVANCED of testing on cars without driver, Google came across a bizarre security nightmare: human beings. Last month, one of his cars without driver approached the crosswalk, and she acted like it is supposed that we should do: he slowed to cross a pedestrian, and its “safe driver” braked. The pedestrian is fine, but not as the Google car, buffered from behind by the driver of a sedan.

The fleet of driverless cars Google is scheduled to observe the rules of the road, and does so to the point. But if you follow the rules of the road literally, it can become very difficult to get around. In a test of 2009 car experimental Google has failed to pass a crossroads where all the stop because its sensors continued to wait for another car with driver would stop altogether and let her go, instead of advancing plan floor. And they knocked the Google robot. (In the US it is not expected before the automatic right in these cases: drivers arrived simultaneously at an intersection to stop more pass in turn, stepping forward and signaling their intention, but the car behind each of them must respect the rounds full of priorities and start over, NDT)

But
this is not a problem only of Google: researchers working in the field of new vehicles without drivers say that one of the biggest challenges of automatic machines is to interact in a world in which human beings do not behave according to the rules. “The real problem is that the car is too safe,” notes Donald Norman, director of the Design Lab at the University of California at San Diego, expert and scholar of autonomous vehicles. “They must learn to be a little ‘aggressive, and what it should become dependent on culture”.

In a world with no human driver, in traffic accidents and deaths could very well drop to nothing, as some scientists predict. However, the extensive use of cars of this type is still very far away in time, and the testers are trying to identify the hypothetical risks – for example, hackers – and the thousand contingencies of the real world, such as what would happen to a car in autonomous driving it breaks on the highway.

for now In the short term there is the problem of figuring out how to interact with robots and humans. Already now there are multiple manufacturers of cars equipped with technology that can alert the driver or replace him in some aspects, through advanced systems of controlling the speed or braking which switch alone. Uber is working on the development of a technology that allows cars to run without a driver in July Google has extended its testing in Austin Texas. Cars Google can regularly make quick maneuvers and evasive or be cautious in ways that are at once the most judicious approach but also out of step with most other vehicles on the street.

Engaged as a test driver in Silicon Valley, Tom Supple says: “This car will always follow the rules. I mean that it will do to the point that drivers in the flesh will wonder why that car is behaving well?”.

Since 2009 cars Google You found themselves involved in 16 accidents, mostly minor, and in any case, the company said that it was the fault of the driver in the flesh. Among these incidents there is also the curtain back on August 20, Google announced Tuesday. The machine in autonomous driving has slowed to a pedestrian crossing, and its test driver intervened braking manually. The car was hit, and the Google employee was taken to hospital for a mild whiplash. In Google report on the incident, you learn something specific: the “Safe Driver” by pressing the brakes did the right thing, but if the car had acted entirely alone could curb less abruptly and get closer to the crosswalk, giving the driver of the car behind more time to brake. In any case, Google says it is impossible to know if that would have avoided the collision.

During a recent test in the presence of some journalists of the “New York Times”, the Google car made two evasive maneuvers that have demonstrated how the machine wrong for excessive caution. With a first maneuver has abruptly swerved to avoid colliding with a parked car bad, so bad that the sensors Google believed he was onto traffic. Soon after, approaching a red light, has upset the passengers on board because the laser detection system mounted on the roof has noticed that a vehicle coming from the opposite direction was approaching the red at a rate deemed unsafe. The machine of Google, also in this case, has swerved sharply to the right to avoid the possible collision. Ultimately, however, the other car did what I often do drivers in the flesh: she approached a red light without the necessary prudence, and has held back only to last.
