McAfee researchers found that placing a two - inch section of black electric tape over part of a 35 mph speed limit sign tricked a Tesla car into reading the sign as 85 mph . The car, which was operating in the Autopilot mode, then accelerated beyond the speed limit. McAfee wrote in a blog post on the

It turns out all it needs to fool a Tesla's camera system is a little tape.

  Apple's best-kept secret is its refurbished Mac store, where you can get the latest 16-inch MacBook Pro for almost $400 off Apple's refurbished store is the best place to get Apple devices for several hundreds less than if you bought them brand new I've only bought a MacBook Pro in 2017 from Apple's refurbished Mac store, but the experience was so good that I recommend it to anyone who asks. Most recently, Apple's latest 16-inch MacBook Pros appeared in the refurbished store, and it's the best way to get this laptop without paying the full price of a brand new unit. $US360 might not seem like much of a discount when you spend over $US2,000 on a new laptop, but there's a lot of stuff you can buy for that cash.

What is the car's acceleration? How far does the car travel while it accelerates ? Please show steps cause I can't find any examples. Thanks. d= (vf^ 2 - vi^ 2 ) / 2 *a.

Two security researchers managed to trick two Teslas into accelerating well past the speed limit - by fooling their camera systems into misreading a speed sign. We first saw the news via MIT Technology Review.

McAfee researchers Steve Povolny and Shivangee Trivedi stuck two inches of black tape on a 35mph speed sign, slightly elongating the middle line in the "3".

They then drove a 2016 Tesla Model X towards the sign with cruise control enabled.

Cruise control is a feature of Tesla's autopilot which is supposed to control the car's speed and keep it a safe distance behind the car in front of it.

As the car approached the altered sign it misread it as 85mph, and started to accelerate by 50mph.

The same happened in a 2016 Model S.

McAfee disclosed the research to Tesla and MobilEye EyeQ3, the company which provides the Tesla 2016 models with their camera systems, last year. Tesla declined to comment to MIT Tech Review but said it would not be fixing hardware problems on that generation of vehicles.

The massive screen on Samsung's new Galaxy S20 Ultra phone is so big it would have been considered a tablet less than a decade ago

  The massive screen on Samsung's new Galaxy S20 Ultra phone is so big it would have been considered a tablet less than a decade ago The new Samsung Galaxy S20 Ultra has a screen measuring 6.9 inches, just 0.1 inches shy of the 7-inch screen from the Google Nexus 7 tablet from 2013. If this new Galaxy S20 Ultra smartphone were released back then, it probably would have been considered a tablet. Samsung is no stranger to making phones with giant screens. Its first Note phone from 2011 had a 5.3-inch screen that was massive compared to the 2011 iPhone 4s, which had a minuscule 3.5-inch screen. Visit Business Insider's homepage for more stories.

So, Texas wants to raise the speed limit to 85 mph . What do I think? Well, to tell you the truth, I usually drive 5 mph under the speed limit. The work energy principle says that the work done on an object is equal to its change in energy. If I take the spring and car as my system, then there is no work done on

Analog tape systems run at a variety of speeds depending on type. Pitch fluctuations of one or two per second are classified as wow, while faster variations are called flutter. Wow and flutter are almost never an issue in digital recorders because tape speed has no direct effect on the pitch of the audio

MobilEye EyeQ3 dismissed the research.

A spokesperson told MIT Tech Review the modified sign could have been misread by a human and said the camera hadn't been designed specifically for fully autonomous driving which they said will use a variety of technologies including "crowdsourced mapping" to support cameras.

Tesla's newer models use proprietary cameras, and MobilEye EyeQ3 has released newer versions of its cameras since then which when tested by McAfee were not fooled by the modified sign.

McAfee researcher Steve Povolny told MIT Tech Review that the findings are still concerning, as plenty of 2016 Teslas are still on the roads. "We are not trying to spread fear and say that if you drive this car, it will accelerate into through a barrier, or to sensationalize it. The reason we are doing this research is we're really trying to raise awareness for both consumers and vendors of the types of flaws that are possible," he said.

How A Piece Of Tape Tricked A Tesla Into Reading A 35MPH Sign As 85MPH

  How A Piece Of Tape Tricked A Tesla Into Reading A 35MPH Sign As 85MPH Researchers have identified a potential issue with sensors used in some older Tesla models that misinterpreted speed signs to read the speed limit as 50 miles per hour greater than the sign stated when a piece of electrical tape slightly obscured one of the numbers. The issue was identified as part of 18 months of research by McAfee researchers Shivangee Trivedi and Mark Bereza, who sought to examine the ways that machine learning could potentially be exploited, specifically in the case of autonomous vehicles.

Tesla ' s autopilot has made its first speeding offence. The feature is designed to use a range of sensors to maintain a car's speed , keep a safe distance from the car in front But in a recent test-drive of the system using a Model S, Tesla got pulled over for doing 75 mph (120km/h) in a 60 mph (97km/h) zone.

The safety of Tesla's autopilot systems is under close scrutiny. Last year the National Highway Traffic Safety Administration launched a federal probe into two fatal Tesla crashes in which it determined the autopilot had been 0n.

The company is also fighting a lawsuit against the wife of Walter Huang, an Apple engineer who died after his Tesla crashed into a motorway barrier while on autopilot.

According to Huang's wife, he had complained about the car's autopilot veering towards that same barrier multiple times before. Data released by the National Transportation Safety Board last week confirmed the claims, per Ars Technica.

Currently, Tesla emphasises that its autopilot tools are not meant to make the car fully autonomous, and drivers must always keep their hands on the wheel. But CEO Elon Musk insists that he intends to make Teslas fully self-driving in the near future.

Last year the tech billionaire claimed the company would have a "feature-complete full self-driving" vehicle by the end of 2019. He was forced to walk back that prediction during Tesla's Q4 earnings call at the beginning of 2020 but still suggested full self-driving is just on the horizon. "It's looking like we might be feature-complete in a few months," Musk said.

Yet another major firmware bug has been found that leaves billions of phones, routers, and other wireless devices from Apple, Google, Amazon open to spying. The bug, known as “Kr00k,” was discovered by the ESETt data security firm and disclosed in a recent paper. Kr00k affects the way certain Wi-Fi chips encrypt data; when an affected Wi-Fi device is disconnected, in-progress communications are left improperly encrypted with a key of only 0s, which can be easily decrypted. Hackers can destabilise a Wi-Fi signal to trigger the bug, then intercept and read bits of the vulnerable data.
