The Insurance Institute for Highway Safety (IIHS)
The Insurance Institute for Highway Safety (IIHS) , in a paper titled “Reality Check,” issued the warning after testing of five of the systems from Tesla, Mercedes, BMW and Volvo on a track and public roads. The upshot is the so-they can save your life, the systems can fail under many circumstances.
“We have found the situations where the vehicles are under semi-automated control. “said David Zuby, the institute's chief research officer.
Among the scariest found in the system is Tesla vehicles, the Model S and Model 3. The system has been turned off, but automatic braking on. At 31 miles per hour (50kmph), both Teslas braked and mitigated a crash but still hit a stationary balloon.
They were the only two models that failed to stop in time during tests on a track. Yet when the adaptive cruise control, which keeps the set distance from cars in front, is activated, the Teslas braked earlier and gentler and avoided the balloon, the agency said.
On the road, the institute's engineers found that all the vehicles but Tesla's Model 3 failed to respond to stopped vehicles ahead of them, the institute said. The systems tested, in the Teslas, BMW's 5-Series, the Volvo S-90 and the Mercedes E-Class, are among the best in the business right now and have been rated “superior” in previous IIHS tests.
Zuby said the systems do increase safety but the tests show they are not 100% reliable. Many of the scenarios discovered by IIHS are covered in the vehicles. But Zuby said not many people read their owner's manuals in detail.
Even though the systems have names like Tesla's “Autopilot” or Volvo's “Pilot Assist,” they are not self-driving vehicles, Zuby said. “They will help you with some steering or speed control, but you really will not be paying attention to them right away,” he said.
Many of the cars' lane-centering systems failed, especially on curves or hills. The BMW, Model S and Volvo “steered toward or across the lane line regularly,” requiring driver intervention, the IIHS said.
The IIHS-affiliated Highway Loss Data Institute analysed features on the Model S were helpful in reducing property damage and bodily injury claims.
But adding “Autopilot,” which includes automatic steering and lane-changing, only helped to lower collision claims. The institute, which in the past has developed tests that is made in the form of a car, it.
The group also said that a pedestrian death in Arizona involved an Uber autonomic vehicle shows the dangers of testing self-driving vehicles on public roads. IIHS is developing for the benefit of drivers and systems will eventually make recommendations on regulations for fully autonomous vehicles, Zuby said. The messages were on the left. – AP
