Tesla and the U.S. National Transportation Safety Board (NTSB) are both investigating the fatal accident involving a Model X Autopilot in Mountain View last month, but now another Tesla owner also conducted his own little investigation into the accident by following a similar scenario on Autopilot and almost crashed on video by doing so.

Tesla said Thursday it was recalling a huge number of its Model S sedans around the world over a power steering issue. It told customers in an email that it was a proactive move and none of the company’s other vehicles were affected.

Below are transcripts of three 911 calls from Apple's new campus, obtained by The Chronicle via a public-records request. The calls, all made in January, relate to injuries suffered by people who walked into glass at the campus, which is called Apple Park. The transcript has been lightly edited. Click here for a story about how a Cupertino official had warned Apple last year about the problem.

Whatever their physiological effects, the most immediate threat of these nicotine-delivery devices comes from a battery problem called thermal runaway

In the last couple weeks, both my girlfriend and I have come within inches of being hit by cars while walking, in crosswalks, in downtown Seattle. Unfortunately this isn't the only time that's happened to us, nor is it exclusive to us or this city. Every single day in every city I visit, I see drivers blow through lights, stop in crosswalks and generally disrespect pedestrians. What's obviously changed in the last few years is the root cause: people aren't necessarily more rude or worse drivers, they're just trying to use their phones while driving.

Miners are contracting the disease with striking frequency and at younger ages than ever before. By Marissa Fessenden.

The drowning deaths of six people during a whale watching trip off British Columbia have been classified as accidental by the province's coroner's service.

In October 2003, Billy Wayne Woods and his family packed into a luxury $181,000 motorhome for a fun getaway to Florida. Call it a textbook American vacation: their destination was Disney World, and with his wife, Shirley, his son and daughter-in law and two grandchildren in tow, the trip would surely be one to remember. But on the return home for the Alabama family, the vacation took an abrupt turn for disaster.

Dizziness, nausea, and vomiting are not things typically associated with a drive to the store. But after more than 1,300 complaints of similar symptoms reported, the National Highway Traffic Safety Administration ( NHTSA) says it is investigating Ford Explorer SUVs. They are looking at models from the years 2011-2017. Ford says they haven't found any problems that could explain why someone would develop those symptoms. The automobile manufacturer even says the SUVs are safe to use.

In India, more than 150,000 people are killed each year in traffic accidents. That’s about 400 fatalities a day and far higher than developed auto markets like the U.S., which in 2016 logged about 40,000.

From the collection out on garbage trucks, to the processing at transfer stations and recycling centers, to the dumping at landfills, the waste industry averages about one worker fatality a week. Nationally, in 2016, 82 percent of waste-worker deaths occurred in the private sector.

In the past fifty years, the car crash death rate has dropped by nearly 80 percent in the United States. And one of the reasons for that drop has to do with the “accident report forms” that police officers fill out when they respond to a wreck. Officers use these forms to document the weather conditions, to draw a diagram of the accident, and to identify the collision’s “primary cause.”

The rollout of fully autonomous cars may depend on how the public responds when they crash.

Self-driving cars have often been touted by industry experts as a safer alternative to human drivers. Whereas humans frequently engage in poor and reckless behavior on the road—nearly 1.3 million people die in road crashes globally each year, according to the Association for Safe International Road Travel—robocars would neither get tired nor drunk, and will generally drive with greater precision.

The Consumer Product Safety Commission tried for 16 years to make portable electric generators less dangerous. Then a Trump-selected official took charge of the agency.

Amazon could face $28,000 in potential fines after an inspection by the state of Indiana found potential workplace safety violations at a warehouse where a 59-year-old worker was killed in late September. The Associated Press reported that the victim, Phillip Terry of Indianapolis, “was fatally crushed when a forklift’s lift fell on him while he was doing maintenance work on it.” Terry was killed on Sept. 24 at an Amazon facility in the Indianapolis suburb of Plainfield.

At least two police departments in Massachusetts are warning parents to inspect their children's Halloween candy for marijuana edibles. But there has never been a recorded case of any one giving cannabis candy -- or razor blade apples, or poisoned Kit Kat bars -- to trick or treaters, according to fact checkers and a University of Delaware professor who studies Halloween poisoning myths.
