The cat and the laser-pointer;

A team of researchers in Israel have successfully tricked Tesla’s and Mobileye’s driver assistance features into stopping for pedestrians that weren’t there, and driving at speed limits posted on signs that don’t exist, exposing a possible flaw in modern automotive tech that could prove dangerous if exploited.
 
Researcher Ben Nassi from Ben-Gurion University just recently fooled a Tesla Model X running Version 2.5 hardware using a simple video projector. Nassi had previously fooled a Mobileye 630 Pro driver assist system with the same device. Nassi calls the system “Phantom of the ADAS.”

New footage has emerged showing the moment a Tesla electric vehicle driving on Autopilot crashed into the back of a truck in California earlier this month.
 
The driver posted the video online, describing in a summary of the footage the moment when the unknown model Tesla experiences the Autopilot failure on January 13 while driving in Milpitas, in the San Francisco Bay area. […]

 
Drivers have reported several similar problems with auto pilot. A federal probe into a 12th Tesla crash in December, that was believed to be tied to the auto pilot system, which already had been blamed for four fatal accidents

“Twitter sentiment is a Styrofoam iceberg”.

If you’d prefer reasoned debate, it will start with a collective realization that mobs can’t do much except make noise. They’re not actually very big, for starters — the number of people who replied to Rowling’s tweet wouldn’t fill most Texas college football stadiums, and reasonable people don’t choose their views by polling the crowd at the Aggies-Longhorns game.
 
More important, most mobs aren’t committed to the effort beyond flicking a thumb. Institutions that ignore the mob are often astonished at how little difference all the outrage makes to their business — and I’d bet Rowling won’t see much evidence of this controversy in her royalty statements.
 
The censorious power of Mrs. Grundys always depends on the cooperation of the governed, which is why their regime collapsed the moment the baby boomers shrugged off their finger-wagging. If Rowling provides an unmissable public demonstration that it is safe to ignore the current crop, we can hope others will follow her example, and the dictatorship of the proscriptariat will fall as quickly as it arose.

Daily Wire;

The Washington Post hacked into a Chevy Volt several days ago with the help of a automotive technology expert to find out just how much automakers are spying on their owners and discovered that vehicles are recording their owners’ every move.
 
The Post used a 2017 Chevy Volt for its experiment and learned that the car collected a wide range of highly precise data ranging from the vehicles location to information about the driver’s cell phone, including call records — noting that many vehicles copy over personal data the moment that a smart phone is plugged into the vehicle.

Be sure to read it all.

They’ll pry my 2002 Astro from my cold, dead hands.

As Fowler writes, “My Chevy’s dashboard didn’t say what the car was recording. It wasn’t in the owner’s manual. There was no way to download it.”
 
To figure this out, Fowler had someone hack into the Volt. He discovered that the car was recording details about where the car was driven and parked, call logs, identification information for his phone and contact information from his phone, “right down to people’s address, emails and even photos.” In another example, Fowler bought a Chevy infotainment computer on eBay and was able to extract private information from it about whoever owned it before him, including pictures of the person the previous owner called “Sweetie.”
 
While GM was the subject of Fowler’s experiments, it’s not the only company collecting data on its drivers.

Every minute, an estimated 3.8 million queries are typed into Google, prompting its algorithms to spit out results for hotel rates or breast-cancer treatments or the latest news about President Trump.
 
They are arguably the most powerful lines of computer code in the global economy, controlling how much of the world accesses information found on the internet, and the starting point for billions of dollars of commerce.
 
[…]
 
Over time, Google has increasingly re-engineered and interfered with search results to a far greater degree than the company and its executives have acknowledged, a Wall Street Journal investigation has found. […]
 
• Despite publicly denying doing so, Google keeps blacklists to remove certain sites or prevent others from surfacing in certain types of results. These moves are separate from those that block sites as required by U.S. or foreign law, such as those featuring child abuse or with copyright infringement, and from changes designed to demote spam sites, which attempt to game the system to appear higher in results.
 
• In auto-complete, the feature that predicts search terms as the user types a query, Google’s engineers have created algorithms and blacklists to weed out more-incendiary suggestions for controversial subjects, such as abortion or immigration, in effect filtering out inflammatory results on high-profile topics.
 
• Google employees and executives, including co-founders Larry Page and Sergey Brin, have disagreed on how much to intervene on search results and to what extent. Employees can push for revisions in specific search results, including on topics such as vaccinations and autism.
 
• To evaluate its search results, Google employs thousands of low-paid contractors whose purpose the company says is to assess the quality of the algorithms’ rankings. Even so, contractors said Google gave feedback to these workers to convey what it considered to be the correct ranking of results, and they revised their assessments accordingly, according to contractors interviewed by the Journal. The contractors’ collective evaluations are then used to adjust algorithms.
 
THE JOURNAL’S FINDINGS undercut one of Google’s core defenses against global regulators worried about how it wields its immense power—that the company doesn’t exert editorial control over what it shows users. Regulators’ areas of concern include anticompetitive practices, political bias and online misinformation.
 
Far from being autonomous computer programs oblivious to outside pressure, Google’s algorithms are subject to regular tinkering from executives and engineers who are trying to deliver relevant search results, while also pleasing a wide variety of powerful interests and driving its parent company’s more than $30 billion in annual profit. Google is now the most highly trafficked website in the world, surpassing 90% of the market share for all search engines. The market capitalization of its parent, Alphabet Inc., is more than $900 billion.

To the surprise of no one.

NYT (Outlined);

Researchers in Japan and at the University of Michigan said Monday that they had found a way to take over Google Home, Amazon’s Alexa or Apple’s Siri devices from hundreds of feet away by shining laser pointers, and even flashlights, at the devices’ microphones.
 
In one case, they said, they opened a garage door by shining a laser beam at a voice assistant that was connected to it. They also climbed 140 feet to the top of a bell tower at the University of Michigan and successfully controlled a Google Home device on the fourth floor of an office building 230 feet away. And by focusing their lasers using a telephoto lens, they said, they were able to hijack a voice assistant more than 350 feet away.
 
Opening the garage door was easy, the researchers said. With the light commands, the researchers could have hijacked any digital smart systems attached to the voice-controlled assistants.
 
They said they could have easily switched light switches on and off, made online purchases or opened a front door protected by a smart lock. They even could have remotely unlocked or started a car that was connected to the device.

I wonder what they could do with a lidar sensor?
