the wheels of your car are revealing your position to anyone who wants to monitor you

I can think of few uglier scenarios behind the wheel than a puncture going 120 kilometers per hour. Fortunately, tire pressure sensors minimize this risk because they act as whistleblowers in case of mishaps, ranging from a blowout to a simple loss of pressure. They were designed with security in mind and not privacy and that has opened a door: monitor where your car passes. And obviously, where are you. Context. Tire pressure monitoring systems or TPMS are required by law: in the EU since 2014, also in the pioneering United States and other countries such as South Korea or Japan. This system uses small sensors integrated into each wheel to monitor the pressure and send wireless signals to the car’s computer to alert the driver if a tire drops below the set pressure. Due to regulations and validity, there are millions of vehicles in circulation with TPMS and no one perceives them as a risk: they are safety sensors, not connectivity. The discovery. A research team from IMDEA Networks has shown that TPMS sensors continuously emit a unique identification number via radio frequency that has neither encryption nor authentication. The ID does not change, so it works as if it were a license plate. Like that radar that catches you on a specific day and time at a certain point. Thus, anyone with a radio receiver can pick it up and if they do it once, from then on they will be able to recognize that car at any other time. This operation occurs without the driver knowing and, furthermore, he cannot do anything to avoid it. Why is it important. To begin with, because the research team has already confirmed that by crossing the four data from the four wheels, the reliability of the identification is high. Alessio Scalingi, professor at UC3M and one of the authors of the study, summarizes it like this: “data that seems passive and harmless can become a powerful identifier when collected at scale.” But it is also much more discreet than a conventional radar or camera: the TPMS emits radio signals continuously and these are invisible and can pass through obstacles or walls. Hiding is not an option. On the other hand, there is no need to hack anything: the signal is public and by default it arrives unencrypted. In short: TPMS tracking is cheap, difficult to detect, and difficult to avoid. How they did it. To reach this conclusion, the IMDEA Networks Institute research team together with European partners conducted a 10-week study in which they collected signals from more than 20,000 vehicles. The equipment used was a network of low-cost SDR radio receivers ($100 each), which were distributed near parking lots and roads. In that time they were able to collect more than six million messages, which helped them to reconstruct routes and routines, for example what time someone arrives at work or how often they go shopping, the type of vehicle or even whether it transports heavy cargo. The receivers are capable of capturing signals from moving cars at more than 50 meters, even if the sensors are hidden or inside buildings. How it affects you as a driver. You are potentially exposed to monitoring of your car journeys no matter what you do. This sensor goes inside the wheel and has no switch, so as a driver you cannot do anything to avoid this tracking beyond obviously not using your private vehicle. Of course, it requires someone to deploy this network of receivers deliberately. The ball is in the regulators’ court. As the research team explains, the real problem is structural: the TPMS regulations do not require encryption for these sensors, so the solution is not in the hands of users, but in those who regulate and the manufacturers. As concludes Dr. Yago Lizarribarone of the authors of the study: “Our findings demonstrate the need for manufacturers and regulatory bodies to improve the protection of future vehicle sensor systems.” In Xataka | The industry has been filling cars with complex safety systems for years.

South Korea has designed a rover with wheels that change size to explore them

The dream of colonizing the Moon has been around since we set foot in it more than five decades ago. Settling on our satellite poses innumerable challenges; from how to get oxygen, what the food should be likeeven of course what is the best place to do it. We already have an answer to the latter: in caves. The problem is that you have to explore them first. A new rover. They count in Futurism that a team of South Korean scientists and researchers have designed a rover specially designed for the exploration of these lunar caves. The work has been published in Science Roboticswhich includes a video showing how the rover is capable of moving through difficult terrain, withstanding extreme temperatures and even being launched from a drone without suffering damage. The key is in the wheels. They are made up of metal sheets assembled to form a type of helix. The peculiar thing is that the wheels are soft and are capable of changing their diameter from 23 to 50 centimeters. This makes it much easier for you to overcome obstacles, enter smaller gaps when necessary, and also cushion falls. It is a very simple design, without hinges or bearings or complex parts; They simply fold or unfold by torsion, as if they were a spring. Moon cavesyes. As we said, there are many, but the main one is that the conditions are extreme. During the day, the temperature can reach 127ºC and at night it drops to -173ºC, which is not feasible. There is also the problem of long-term radiation. This is on the surface, but there is good news and that is that the Moon has a series of pits or caves where the temperature is much more stable, around 17ºC. A lunar tunnel. There is still more. By mid-2024 NASA discovered a huge cave in the Mare Tranquillitiatis crater, near the area where the Apollo 11 mission landed in 1969. It is estimated that the cave (actually a lava tube) measures about 45 meters wide and reaches up to 80 meters long, and the ground is also quite flat, so placing a settlement inside it could be viable. At the moment this cave has not been explored, although Solutions have already been proposed to do so. Artemis Program. Returning to the Moon is one of the most important space projects currently underway. Artemis It not only proposes setting foot on our satellite again, but also establishing our presence on it. The first unmanned mission was launched in 2022 and the plan is that Artemis II takeoff in February 2026. Artemis III will be the first manned mission, although this could still be missing several years. Image | Kaist In Xataka | We are sending cannabis samples to space.

a suitcase with wheels at 30 km/h

Just a few days ago, Pere Navarro, director of the DGT, said that “The only way to access the cities will be by public transport“. These are words that a good part of the media has used to advance supposed prohibitions about which nothing has really been said. But they do reflect another battle: the battle for space. For years, European cities they have put up a battle with the cars and they are redistributing space. The large pedestrian areas such as those in Barcelona, ​​the mandatory ZBEs in Spain or the commitment to cycling in Paris are good examples. But it is a movement that has been brewing for decades. What happened to the Scalextric de Atocha? Did you know that Amsterdam was once part of the car paradise? These same debates were already taking place in Japan more than 30 years ago. And when one lives in overcrowded populations and with very high population densities, having or not having a car is no longer a question of purchasing power, it is a question of how that can impact our own environment. These questions of how many cars there should be in a city and what implications they have is what led Japan to implement the Shako Shomeishothe regulations that prevent you from buying a car if you do not have a secured parking space. At least in the busiest cities. In that same context were born the kei carespecially narrow and small cars with specific regulations to avoid being subject to taxes and that Shako Shomeisho that limits the purchase of vehicles. The concept wants to repeat in Europe although if it has triumphed in Japan it is because it is deeply rational, something that does not always go well with the European idea of ​​the automobile. And since in Japan the radically rational triumphs and they are decades ahead when it comes to space management, already in the 80s and 90s they were wondering what mobility solutions They could arrive in the future to move us around in a motorized vehicle, taking up as little space as possible. With those, Mazda pulled an ace up its sleeve. One in suitcase format. The Mazda Suitcase Car or the “suitcase car” The 90s had just begun and Mazda wanted to look for original mobility solutions. Playing the typical Futurology game that It is made in design centersthe Japanese company opened an internal competition to receive proposals for a groundbreaking vehicle. It is very likely that the executives who received Yoshimi Kanemoto were already expecting that the designer who led the Mazda Suitcase Car project would arrive with the proposal in a suitcase. We imagine, of course, that not in the way they expected. Because that suitcase did not hide sketches, design games or feasibility studies. What he was hiding was the very vehicle that had been requested. With the help of Kanemoto, a group of engineers gave life to the Mazda Suitcase Cara small three-wheeled vehicle that moved thanks to a two-stroke engine. The chassis? The suitcase itself, of course. And it is in the same suitcase where the humble apparatus of the vehicle is stored in which the… driver sits? Or pilot, rather. In this video You can see how it has just enough space to store the engine, the tank and the three wheels. Once assembled, it is as simple as getting on and starting to roll, driving this kind of three-wheeled kart with a handlebar that includes a handle to give gas, like on a motorcycle. The prototype, obviously, did not reach production but it was an example of how far technology could go to miniaturize the components necessary to make a vehicle roll. The company itself explains that the prototype was born as an idea to anticipate what vehicles would be like in the year 2020. For its Japanese designer, we would move in a 57×75 cm Samsonite suitcase in which a small kart with the capacity to reach 30 km/h would be hidden. It’s no small thing. The idea, however, was presented outside Japan. In 1992, Associated Press photographed to one of the company’s executives riding the device in the middle of Times Square, in the days before a New York Auto Show. Obviously, the proposal went nowhere but we would have to ask Kanemoto what he thinks of those who cross half the world today to get on a kart, dress up as Mario Bross and ride through Tokyo traffic as if they were experiencing a Mario Kart race.

For a reason as stupid as fun, someone put six wheels and two engines to a Renault 5 Turbo. And the result was great

Six -wheeled cars have always generated some fascination. From The famous Tyrrel P34 with which Jody Scheckter managed to win a Formula 1 career to the Mercedes G63 AMG 6×6 that became famous for their huge presence and their ability to overcome any obstacle in the desert. The story we bring today has a bit of the first and a lot of the second. The first because, we could think, a Renault 5 Turbo has much more to do with a “little” Tyrrel P34 (at least if we think of its 4.32 meters long for the 5.63 meters maximum that can measure a formula 1 current) that with a gigantic three -axis mercedes. But it also has the second because the original germ of this RENAULT 5 SIX TURBO He was born with the idea of ​​overcoming any obstacle that was presented to him along the way. Any obstacle that, for example, could be found in the Dakar. Yes, in the Dakar. A very crazy Dakar as advertising Those who approach the departure of the Paris-Dakar rally in 1980 had to find a picture as wonderful as amazing. As soon as you could meet four fools who intended to cross Africa with a Vespa as a modified Renault to shelter six wheels. Because that was, exactly, the great objective for which Cristian de Léotard He took the base of one of the most iconic sportsmen of those days to turn it into a three -axis car, six wheels, two engines and, of course, two gearboxes. Léotard was specialized in such modifications and, in fact, he had already experienced with a six -wheel cytroën C15. Did you think that the performance of the mythical van could not be improved? It would not be his only great work. In fact, the Mercedes Class G 6×6 has its origin in the workshop of this French coach. But its most striking, rare and iconic creation is, of course, the Renault 5 Turbo 6×6. Animated by his passion for mechanics and careers OffroadLéotard was gaining experience working within Tissier, a body company specialized in all types of extravagances, such as a Citroën Cx Camperized that seemed to keep a whole city within itself. Over the years, Léotard took his own way to found ADPL (Applicaton Defés Léotard) That, without a doubt, it seems a tribute to ADPT (Applicaton Deféés Tissier), the company in which it grew laborily and in which it sought all possible solutions to create a six -wheel range. That must have been the germ of his craziest project: take two Renault 5, paste them, get him to work with six wheels and face the Dakar sand. And he did it with great success if we attend to the figures. The engendro did not go too much as a mother (4.21 meters that are 10 centimeters more than a RENAULT 4 Current Electric) and only added 100 kg to the whole, being below the ton, as they explain in 12 cylinders. The image was so powerful that I couldn’t miss the opportunity. If I wanted to sell its creation to new customers, it had to show that the car was not only functional, it should also be resistant. The Dakar and its hardness were their best chance and tried to make the most of it. Although he had to retire due to mechanical problems, the rally had generated enough advertising to make a name in the market and, of course, the reference for all those crazy people who wanted to put two extra wheels to their Renault 5. Six wheels, two engines and two gearboxes One of those crazy people in charge of what would be one of Léotard’s most extravagant projects. Make a Renault 5 Turbo a six -wheel car fully functional and effective. To maintain the sports essence of the car and do it as extreme as the original, Léotard returned to “paste” two Renault 5 But this time he also took the opportunity to install a second engine on the front. The Renault 5 Turbo It is pushed by a propeller that sends all its force to the rear wheels. So that it was also effective from the front axle it was decided to install A second engine of Alpine origin 93 hp under the front hood to send the force to the front wheels. Click on the image to go to the original publication They explain in Motorpasion that Léotard described his invention as “a train with two locomotives.” To operate the two engines, the car had two boxes of independent changes and, therefore, with two levers in the front area that were synchronized. The car was, without a doubt, the result of the good work with its project for the Dakar. A car that, in the words of Sixmania (Where you can check more project photographs), it got a much more effective braking than that of the original vehicle, since the drum brakes had been replaced with brake discs on all its wheels. In addition, they assured that stability had improved and offered enormous performance in irregular land. This version Offroad Yes, it survived but the turbo version of this strange Renault 5 6×6 cannot say the same. At the beginning of the 2000s, The car suffered a fire that left it shattered almost entirely. The restoration was never achieved before Cristian de Léotard died in 2014 although in Secret Classics They ensure that a last collector did with what was left of the car to try to return it to life.
