Laser hack of self-driving cars can ‘delete’ pedestrians

<p>Although a city filled with entirely self-driving cars is still in the realm of science fiction, more and more cars are <a href="https://en.wikipedia.org/wiki/Tesla_Autopilot" target="_blank" rel="noopener">coming with ‘self-driving’ features so</a> it’s a little alarming to learn that there are ways to use lasers to mess with the technology the cars use to detect its surroundings.</p> <p><a href="https://arxiv.org/abs/2210.09482" target="_blank" rel="noopener">In a study uploaded to arXiv</a> by a team of researchers in the US and Japan, researchers were able to trick the ‘victim vehicle’ (their words not ours) into not seeing a pedestrian or other object in its way.</p> <p>Most self-driving cars use LIDAR to be able to ‘see’ around them by sending out a laser light and then recording the reflection from objects in the area. The time it takes for the light to reflect back gives the system information about how far away the object is.</p> <p>This new ‘hack’ or spoof works because a perfectly timed laser shined onto a LIDAR system can create a blind spot large enough to hide an object like a pedestrian.</p> <p>“We mimic the LIDAR reflections with our laser to make the sensor discount other reflections that are coming in from genuine obstacles,” <a href="https://www.eurekalert.org/news-releases/969698" target="_blank" rel="noopener">said University of Florida cyber security researcher professor Sara Rampazzi.</a></p> <p>“The LIDAR is still receiving genuine data from the obstacle, but the data are automatically discarded because our fake reflections are the only one perceived by the sensor.”</p> <div class="newsletter-box"> <div id="wpcf7-f6-p221287-o1" class="wpcf7" dir="ltr" lang="en-US" role="form"> </div> </div> <p>Although the technology is relatively simple, the attack isn’t an easy one. The team demonstrated the attack up to 10 meters away from the car, but the device must be perfectly timed, and move with the car to be able to keep the laser pointing the right way.</p> <p>The researchers have already told manufacturers about this potential exploit and have suggested ways to be able to minimise the problem. Manufacturers might be able to teach the software to look for the tell-tale signatures of the spoofed reflections added by the laser attack.</p> <p>“Revealing this liability allows us to build a more reliable system,” <a href="https://www.eurekalert.org/news-releases/969698" target="_blank" rel="noopener">said first author, University of Michigan computer scientist Yulong Cao.</a></p> <p>“In our paper, we demonstrate that previous defence strategies aren’t enough, and we propose modifications that should address this weakness.”</p> <p>This unfortunately isn’t the first time that researchers have found <a href="https://cosmosmagazine.com/news/tricking-driverless-car-sensors/" target="_blank" rel="noreferrer noopener">vulnerabilities with LIDAR sensors on self-driving cars</a>, but as more of these problems are uncovered and fixed, the technology will hopefully end up safer in the long run.</p> <p>The research is to be presented next year at the <a href="https://www.usenix.org/conference/usenixsecurity23" target="_blank" rel="noopener">2023 USENIX Security Symposium</a>.</p> <p><img id="cosmos-post-tracker" style="opacity: 0; height: 1px!important; width: 1px!important; border: 0!important; position: absolute!important; z-index: -1!important;" src="https://syndication.cosmosmagazine.com/?id=221287&amp;title=Laser+hack+of+self-driving+cars+can+%E2%80%98delete%E2%80%99+pedestrians" width="1" height="1" /></p> <div id="contributors"> <p><em><a href="https://cosmosmagazine.com/technology/laser-hack-lidar-self-driving-cars-delete-pedestrians/" target="_blank" rel="noopener">This article</a> was originally published on Cosmos Magazine and was written by Jacinta Bowler.</em></p> <p><em>Image: Getty Images</em></p> </div>

Is this the future of pedestrian crossings?

<p>Pedestrian crossings in Melbourne have attracted global attention on TikTok, as Aussies are stunned by the new technology. </p> <p>A TikTok user in Victoria has shared footage of lights embedded into the footpath at crossings that change from red to green to reflect whether you can cross the road or not. </p> <p>The tech has been installed to help "phone zombies" from not getting in an accident in street traffic from staring down at a mobile device.</p> <p>The TikTok user Veronica shared footage of the lights she came across saying, "<span>Bro, look how sick Melbourne is."</span></p> <p><span>"The light across the road is red, so the floor flashes red, and when it's green so you can walk - guess what? The floor flashes green!"</span></p> <p><span>The 12 second clip has racked up thousands of likes, with hundreds of comments being shocked by the relatively new technology.</span></p> <p><span>One person said, "I've been living in Melbourne my entire life and have seen none of these."</span></p> <p class="mol-para-with-font">"I literally live in the city and didn't know this, what?" another commented. </p> <p class="mol-para-with-font">A third user pointed out the lights were installed to protect people who were distracted by their mobile phones when crossing the road.</p> <p class="mol-para-with-font">"It's because people are looking at their phones while walking and are not alert while crossing."</p> <p class="mol-para-with-font">Despite the technology being seemingly rare, the in-ground lights, also known as Tactile Ground Surface Indicators (TGSI), have been installed around the globe since 2017.</p> <p class="mol-para-with-font">Places in Sydney and Melbourne have been adapting to the new tech, following in the likes of South Korea to increase safety around being aware on the road. </p> <p class="mol-para-with-font"><em>Image credits: TikTok</em></p>

Heads up! City bans pedestrians from texting while crossing the street

<p><span style="font-weight: 400;">A new state law in New York would slap stiff fines on pedestrians who text and email on their phones while crossing the street.</span></p> <p><span style="font-weight: 400;">“There will be a green light and people will still be texting in the middle of the street,” cabbie Carlos Rodriguez complained to </span><a href="https://www.washingtonpost.com/"><span style="font-weight: 400;">The Post</span></a><span style="font-weight: 400;"> while waiting near New York’s Penn Station.</span></p> <p><span style="font-weight: 400;">“I stop so I don’t hit the person, then I get a $US110 ($NZD 166) ticket for stopping at a green light. I’m sick of it!” </span></p> <p><span style="font-weight: 400;">The new law is looking to impose fines of $US25 ($NZD 37) to $US50 ($NZD 75) on first-time offenders, while death-wish texters who stride right back into the pedestrian crossing and repeat the offence within 18 months would be hit with fines as high as $US250 ($NZD 378).</span></p> <p><span style="font-weight: 400;">However, backlash is already in the works as pedestrians believe that texting in traffic is their right.</span></p> <p><span style="font-weight: 400;">“What a dumb proposal,” scoffed Chris Werner, 36, who barely looked up from his phone as he crossed West 32nd Street.</span></p> <p><span style="font-weight: 400;">“I’m still going to text while crossing.”</span></p> <p><span style="font-weight: 400;">Alejandro Cerda, 29, agreed as he texted his way across Seventh Avenue at 27th Street.</span></p> <p><span style="font-weight: 400;">“Can we vote these politicians out of office since they’re brain dead?” said the Lower East Side resident.</span></p>

Hollywood superstar tricks pedestrians into thinking they’re spies

<p>In the old days the only thing you needed to do to generate hype for a Hollywood blockbuster was to book a trailer in the upcoming features. But today’s movie studios are increasingly becoming more creative with the way their market their films.</p> <p>And as we see in the video above, the results can be hilarious.</p> <p>In the video clip, to promote upcoming movie, Jason Bourne, Hollywood star Matt Damon cleverly tricks a series of unsuspecting pedestrians into thinking they’re spies.</p> <p>The prank is simple, yet elegant. A stranger is handed a mobile phone by a random passer-by and called by Damon, who then asks them to perform a variety of tasks.</p> <p>They’re asked to do everything from complimenting someone’s children, to buying a hotdog and collect an envelope from a mystery man standing on a nearby bridge.</p> <p>Those who were pranked were eventually guided back to a room in a carpark, where Damon emerged and surprised them with tickets to the film’s premiere.</p> <p>What a funny video. What’s your favourite movie with Matt Damon in it, and do you think you’ll be going to see Jason Bourne?</p> <p>Let us know in the comments.</p> <p><em>Video credit: YouTube / Omaze</em></p> <p>Related links:</p> <p><span style="text-decoration: underline;"><em><a href="/entertainment/movies/2016/06/shocking-actor-transformations-for-movie-roles/" target="_blank"><strong>10 shocking transformations by actors for movie roles</strong></a></em></span></p> <p><span style="text-decoration: underline;"><em><a href="/entertainment/movies/2016/05/most-expensive-films-ever-made/"><strong>The 15 most expensive films ever made</strong></a></em></span></p> <p><span style="text-decoration: underline;"><em><a href="/entertainment/movies/2016/05/8-classic-films-getting-remakes/" target="_blank"><strong>8 classic films getting remakes</strong></a></em></span></p>

The busiest pedestrian crossing in the world

<p>Very rarely are pedestrian crossings must-visit tourist locations in and of themselves, but you don’t have to be at Shibuya Crossing long to see why it’s become an essential part of any Tokyo trip.</p> <p>Shoppers, students, couples, commuters and tourists all converge at this busy junction and when the light turns red they take off in every direction. Yet strangely, there’s a degree of courtesy in the chaos. People are very mindful of their space, and are almost at pains to avoid collisions. </p> <p>Still, if the experience seems a little too chaotic for your sensibilities, you may prefer to get a coffee at the Starbucks overlooking the square. It actually provides the perfect vantage point from which to observe Shibuya Crossing and affords you a moment of respite from the chaos below.</p> <p>If you can brave the crowds the best time to experience the crossing is at a Friday or Saturday night. The lights, and trendy costumes from the locals make it an experience you have to try at least once.</p> <p><strong>How to get there?</strong></p> <p>Shibuya Station is pretty easy to get to from wherever you are in Tokyo. It’s serviced by a number of JR routes as well as Japan’s two subway providers, Toei and Tokyo Metro. If you’re coming from Tokyo Station your best bet is to take the Tokyo Metro Marunouchi line to Shinjuku Station, then change onto the Tokyo Metro Fukutoshin line for a few stops until you end up in Shibuya. Follow the prompts to the Hachiko exit to find the statue and the amazing Shibuya Station crossing.</p> <p><strong>Hachiko</strong></p> <p><img width="500" height="333" src="https://oversixtydev.blob.core.windows.net/media/12080/japan2_500x333.jpg" alt="Japan2 (1)"/></p> <p>The crossing isn’t the only reason to venture to Shibuya however. Shibuya Station features a statue of Tokyo’s most famous dog, Hachiko. This loyal Akita dog came to the station every day to meet his master, a professor, returning home from work. When his master passed away, Hachiko kept coming to the station every day until his own death 10 years later. This story has become a legend in Japan and a small bronze statue was erected in Hachiko’s memory in front of Shibuya Station.</p> <p><strong>What else is there to do in Shibuya?</strong></p> <p><strong><img width="500" height="333" src="https://oversixtydev.blob.core.windows.net/media/12081/jap3_500x333.jpg" alt="Jap3"/></strong></p> <p>Quite a lot, actually! Shibuya is buzzing with life and energy at all times of the day and you can easily find a bar or restaurant to take your fancy in no time at all. Shibuya is also one of the best places for shopping in Japan, so take advantage of the opportunity to embark upon a little bit of retail therapy at one of the many department stores in the region.
