DETROIT — Long emergency stopping distances, difficult-to-use controls and a harsh ride stopped Tesla's Model 3 electric car from getting a recommended buy rating from Consumer Reports. While the magazine said the car has exhilarating acceleration and handling, testers were troubled by its 152-foot average stopping distance from 60 miles per hour in emergency braking tests. The magazine said the distance was worse than any modern car it has tested, and is about 7 feet longer than a Ford F-150, a full-size pickup truck that weighs about twice as much as a Model 3. Tesla said in a statement that its own tests found 60-to-zero braking distances averaging 133 feet. It says stopping distances are affected by road surface, weather, tire temperature, brake conditioning and other factors. It also says it continually does software updates to improve factors such as stopping distance. The Model 3 is Tesla's first attempt to appeal to mass-market buyers. The car that starts at $35,000 but … [Read more...] about Tesla’s Model 3 doesn’t get Consumer Reports’ recommended buy rating

The California Highway Patrol says it used the autopilot of a speeding Tesla to stop the car after its driver fell asleep behind the wheel. The CHP says that around 3:30 a.m. Friday, officers spotted a Tesla Model S doing about 70 mph on U.S. 101 in Redwood City, California. The CHP cruiser pulled behind and used its lights and siren but the driver didn't wake up. Officers then pulled in front and began slowing to a stop, hoping the Tesla's driver-assist feature was on and would do the same. Tesla and other domestic brands landed in the bottom half of Consumer Reports' latest reliability rankings, which covers 29 automakers. The most reliable new cars come from Asian brands led by Lexus, Toyota and Mazda. (Published Thursday, Oct. 25, 2018) Tesla hasn't confirmed whether the car was on autopilot but the tactic worked. The Tesla stopped. Forty-five-year-old Alexander Samek of Los Altos was awakened and arrested on suspicion of driving under the influence.

Is Tesla autopilot killing people? That’s what the National Transportation Safety Board wants to know. A fatal accident involving a Tesla Model S vehicle that happened in Florida should serve as a cautionary tale to drivers in California who are considering purchasing self-driving cars. The accident, which happened in May 2016, was recently blamed on a flaw in the vehicle’s operational design system by the National Transportation Safety Board. Factual background of the accidentOn May 7, 2016, Joshua Brown, a 40-year-old man from Ohio, was driving his Tesla Model S in Williston, Florida. Brown put the vehicle in its autopilot mode, which can control the vehicle while it is driving on highways. While it was in autopilot mode, the vehicle failed to detect a large commercial truck that was crossing the roadway. The vehicle attempted to drive underneath the truck, shearing off its top and killing Brown. Before his death, Brown had been a noted Tesla enthusiast … [Read more...] about Is Tesla Autopilot Killing People?
When the fatal car crash involving a Tesla Model S sedan made headlines last fall, we posted about the accident and predicted that government authorities would classify the crash as being caused by driver error rather than an issue with the “Autopilot” system.Our prediction turned out to be correct. The National Highway Traffic Safety Administration (NHTSA) was still investigating the incident when we first posted about it, but on January 19, NHTSA closed its preliminary evaluation, which found that driver error was responsible.Still, the performance of Automated Driver Assistance Systems, or ADAS, is an area of intense regulatory interest, and it was therefore not surprising to see NHTSA’s Office of Defect Investigation deploy a special crash investigations team to reconstruct the accident.Several news reports have characterized NHTSA as having “exonerated” or “cleared” Tesla of any wrongdoing in connection with the crash. Officially, … [Read more...] about Truly Exonerated? NHTSA’s Tesla Autopilot Investigation
