The Boring Company tunnel is said to be the solution to solving the problem of traffic congestion in the future. The first tunnel about to open is nearly 1.3 km long with 3 stops, can carry 4,400 passengers per hour. Because the length of the tunnel is quite short, the speed of the Tesla operation will be limited to about 56-64 km / h and still have to have a driver behind the wheel, not activated in autonomous mode. It is expected that until the end of this year, Tesla electric cars will be allowed to use Autopilot mode when operating underneath the tunnel. The commissioning of the first underground tunnel system is clearly the important step forward for The Boring Company, to realize their ambition to revolutionize the way people move in the future. hybrid. When there are many active tunnels, a network of underground traffic will form. On the ground there will be stations to bring Tesla cars underground. Then, just turn on autonomous mode and the Tesla car can drive itself to the desired location below the tunnel and be brought back to the ground by the elevator.

To do this, a Consumer Reports expert used a chain to hang a heavy object at the bottom end and tie it to the steering wheel to simulate the presence of a human hand on the wheel. At the same time, the seat belt is also installed pretending that someone is using the driver’s seat. Then, the driver moves to the extra seat and activates Autopilot driving assistance mode. As a result, the Tesla Model Y ran for hundreds of meters on the test track without giving any warning about no one in the driver’s seat. The Tesla Model Y is deceived that someone is behind the wheel and operates in Autopilot mode. Screenshots. Through this test, an expert from Consumer Reports found that Tesla’s system does not use seat sensors and small cameras to track the driver’s eye movement like other manufacturers. Such systems are recently introduced in some Subaru, Ford and General Motors vehicles. Instead, Tesla uses sensors at the steering wheel and seat belts to detect if someone is behind the wheel. Consumer Reports’ experiments have shown weaknesses of this practice. Last weekend, a 2019 Tesla Model S crashed into a tree in the Houston suburbs, Texas (USA), killing two people on the car. Police said they believed that one person was in the front passenger seat and the other was in the back seat at the time of the accident. Before this serious incident, Elon Musk, the CEO of the electric car company, explained on Twitter that the recovered data records showed that the Autopilot was not activated and the car that had crashed did not purchase the Full Self Driving feature. fully self-driving). Tesla believes the car’s Autopilot function won’t be activated without the driver’s seat. But according to Consumer Reports’ testing, it seems that the system is quite easy to be “deceived”.

Currently, Autopilot only offers level 2 autonomous functionality, which only adds active safety features to limit collisions. The driver when activating Autopilot is always warned to put his hand on the steering wheel to intervene when the software does not work as expected. Still, many Tesla owners still find ways to make their cars drive themselves, putting their lives in danger.

Losing your temper when detecting a brake problem will only make it harder for you to handle the brake loss. So, you need to be very calm. Always observe and turn on the emergency lights Not panicking and not attentive to reducing the car speed. Instead, the first thing to do is to observe what is happening in front and behind the vehicle to avoid a collision. Immediately turn on the emergency lights, flash your headlights and use the papyrus continuously so that the vehicles traveling together pay attention to actively give way. Reduce the accelerator A vehicle that loses brakes is when the brake can not be used to control the vehicle’s speed. The most recommended treatment when the vehicle loses brakes is to remove the accelerator or reduce the accelerator pedal. However, if you are traveling in a busy road or going downhill, the driver should not remove the accelerator, just reduce the gas pedal. Because leaving the gas pedal to let the car run freely makes the car more likely to collide with other vehicles, causing more serious consequences. If the car loses brakes while Cruise Control is on, the driver should immediately turn off Cruise Control and reduce the throttle. Absolutely do not turn off the car engine When the car loses the brakes, never turn off the engine. Because turning off the engine will make the car lose steering power, making it difficult for the driver to control the car to avoid obstacles on the road. What’s more, turning off the engine means the car is no longer braked by the engine and transmission. It is even more dangerous for a car to fall into a free-flowing state under the force of inertia. Shift the car to low gear The driver can take advantage of the engine brakes by shifting the vehicle to low gear. For automatic transmission vehicles, the driver only needs to switch to semi-automatic mode, low gear mode or switch gears through the gearshift pad on the steering wheel. For manual gearboxes, the driver only needs to change the gear lever to 1 or 2. But a problem posed is that if the car is running at high speed suddenly, being forced to low gear can cause the car to break down, destroying the transmission system even more dangerous now. Some experts share, when dealing with a lost car, the car should not be put in low gear in the first place. Instead, switch the number by level or 2 levels. For example, if the car is in 5, it can go to 4 or 3, after feeling a more stable speed, continue to gear 2 or 1. Depress the brake pedal continuously Even if the vehicle loses its brakes, try to brake continuously. Because the vehicle may lose its brakes just because the vehicle only loses brake fluid pressure temporarily. Depressing the brake repeatedly can help regain the brake fluid pressure. When the soft feel brake pedal is pressed and the brake pedal is low, it is likely that the vehicle will lose its brake due to a malfunction of the oil line. At this point, you should depress the brake several times. Use the hand brake The handbrake is designed for use when the vehicle is stopped. But in an emergency, you can also use the handbrake to create braking force. However, if you use the handbrake, be careful that you only use the handbrake to brake when the vehicle is traveling at very low speeds. Because using the handbrake while the vehicle is running at high speed can cause the vehicle to lock, lose grip, slip long, leading to dangerous situations such as the vehicle being thrown, the vehicle loses control. Actively collide When the car has lost the brake, the driver should try to put the car on empty roads, rough roads, many stones … so that the vehicle can slow down or combine using a sagging method. In case of force majeure, the driver should choose to handle the last brake, which is to actively let the car crash into a safe obstacle to stop the car.

But what happened five days later is quite the opposite.

Ever Given – a container ship the size of a skyscraper was stranded on the banks of the canal on March 23. And Abdul-Gawad’s boss immediately called him to the scene.

“We need you to get in the car and come now because you are the only excavator driver nearby,” the leader told the 28-year-old male employee, who has been driving the excavator since college.

Abdul-Gawad vs “monster”

Liberating Ever Given was a combined effort, with winch, tugboat and excavator. But Abdul-Gawad was the one who really faced the problem. Once at the base of the ship, Abdul-Gawad had no choice but to start digging.

According to his estimates, the bow of Ever Given was stuck below about 6 meters of ground. The stern is also caught on the opposite shore. The ship blocked the Suez Canal, blocking all traffic.

The image of a tiny excavator facing a giant ship made many people laugh. But for Abdul-Gawad the situation is much less humorous. It is really dangerous.

Taking on the task of shoveling to release the bow, just a small mistake by Abdul-Gawad could cause the ship carrying tens of thousands of containers to collapse.

“I was afraid that the ship would be too tilted on one side or the other. If it leans on me, goodbye the excavator, goodbye Abdul-Gawad.

If you see the contrast between the size of the ship and the size of the excavator, you will find it very frightening. ”

Two other excavators were dispatched to the scene a few days later, but the drivers were too scared to do what Abdul-Gawad was doing. Instead, they were just sticking around clearing the rock that Abdul-Gawad dug.

21 hours / day

Wearing thin flip flops, Abdul-Gawad undertook digging for hours. When the tugs are active, Abdul-Gawad will receive a radio signal to temporarily retreat away.

“But you know, until I dig 5 or 6 meters, there’s still no movement.”

When pictures of Abdul-Gawad’s excavator began to appear on the Internet, he said he felt as if “people were just making fun of me.”

“And that’s what made me more determined. I think, you’re making fun of me so I’ll prove I can do this. ”

Abdul-Gawad said that for several days, he and his colleagues were only allowed to rest at a barracks of border guards nearby.

“They know that if we go home, we won’t be back in about eight or nine hours,” he said.

Abdul-Gawad and his colleagues only slept about three hours a night. One day, only one hour of sleep.

Success

On March 25, a dedicated dredger – Mashhour – participated in the rescue effort Ever Given. Abdul-Gawad’s job at this time was to move soil, rock and sand from the bow of the ship to another place, while the Mashhour knocked silt off the canal.

This concerted effort – with the help of a high tide – brought hopeful signs the next day. And finally, the campaign was successful on March 29. The image of the Ever Given boat escaping made all the workers shout, and the tugboats honk to celebrate.

Abdul-Gawad said he and his colleagues were “half alive from exhaustion.”

“We were pushed to our limits,” said Abdul-Gawad. “But the moment we saw Ever Given off to sea, all fatigue seemed to vanish.”

Scary silence

The Suez Canal is a source of pride in Egypt, being called “Egypt’s Gift to the World” on billboards when it expanded in 2015.

President of Egypt – Abdel Fattah el-Sisi declared: “The Egyptians have ended the crisis of the ship stranded Ever Given despite all difficulties.”

But Abdul-Gawad said he hardly attended any of the celebrations. Apart from a small ceremony held by a newspaper, Abdul-Gawad received little or no official recognition for his role.

“I was invited to a ceremony, where they honor the people who took the ships out to sea.” But it is primarily intended for Suez Canal Authority employees, not including Abdul-Gawad because he works for a subcontractor.

Invitations were also sent to Abdul-Gawad at the last minute only. Because the celebration took place in a city four hours away by car. And Abdul-Gawad received an invitation an hour and a half earlier.

Abdul-Gawad said he felt deeply hurt.

“The Suez Canal Authority patted himself on the chest that they have done a great job. But in the end, without an excavator, the ship wouldn’t go anywhere. It can still get stuck. ”

In an interview on April 8, Abdul-Gawad said that he and his colleagues still have not received overtime pay, even though they work more than 21 hours a day.

However, Abdul-Gawad said he will look back on those extraordinary days with pride.

“This is an achievement,” he said. “At first it was an achievement for Egypt, but it was also an achievement for me. This event can only happen once in my life. Twice at most. It is something to be proud of.”

Lexus LF-Z Concept length x width x height is 4,880 x 1,960 x 1,600 mm respectively, wheelbase 2,950 mm, weight 2,100 kg. This helps the car have a low center of gravity while reducing vibration and noise in the cabin.

The interior of the Lexus LF-Z Concept is followed “Tazuna” language, which means reins in Japanese, is heavily aimed at the driver. This design is inspired by the relationship between humans and horses, communicating through a reins.

The car has an airy space, the cabin is minimalistic and has artificial intelligence (AI) acting as a virtual assistant of the driver. High-end sound system made by Mark Levinson.

AI technology will learn driver behavior, provide driver assistance through voice communication. Lexus believes it will help the driver control the car more efficiently, such as directions, traffic information …

Clock and touchscreen share one module. Functional controls are located around the steering wheel area for easy operator operation.

Lexus LF-Z Concept is equipped with 4-wheel drive system, trade name is DIRECT4, this system can control the electric motor independently, control front / rear wheels separately. Therefore, the car can customize front-wheel drive, rear-wheel drive or two-wheel drive depending on traffic situations.

In addition, torque distribution systems, throttle control or steering wheel control can help the car have better steering reflexes, narrower steering angles but for precise cornering.

Powering the Lexus LF-Z Electrified is a Lithium-ion battery, liquid-cooled, with a capacity of 90 Kw / h; produces a maximum capacity of 536 hp and maximum torque of 700 Nm. Acceleration from 0-100 km / h in 3 seconds, maximum speed 200 km / h. The vehicle is equipped with a charger with a charging speed of 150 kW and a travel distance of 600 km.

Lexus aims to introduce 20 new or upgraded models, of which 10 are hybrid, plug-in hybrid or fully electric by 2025.

According to Defense World, the US Air Force recently announced blueprints for a new fighter jet being developed under the “Next Generation Aviation Advantage” (NGAD) program, which includes including unmanned and manned fighters.

The image shows a triangular flying fighter and its aerial weapons on display as well. The configuration of this fighter is also very different from today’s fighters, the plane is relatively flat, triangular seen from above, has a pair of vertical V-shaped tails and the air intakes located above. fuselage.

The photo shows that this fighter jet has very highly modular characteristics, can quickly replace engines, landing frames … thereby reducing the load of logistics maintenance, missile pods inside. The aircraft is also equipped with a variety of missiles.

The NGAD program was originally proposed as a joint project of the US Air Force and Navy. Although there is still some joint cooperation between the two sides, each side has in turn set up independent offices to research and develop next-generation fighters.

From 2019 to 2025, the budget for the NGAD program of the US Air Force is 9 billion USD, of which the budget for the fiscal year 2021 is 1 billion USD and the budget of the fiscal year 2022 is 1.5 billion USD.

According to the report, the NGAD program aims to complement the F-22 and F-35 fighters, creating a system with multi-domain cognitive capabilities, flexible information and strong operational advantages. air raid attack. The program will apply digital technology to large-scale fabrication and replacement of small components.

This approach is based on the automotive industry’s digital transformation and uses models to solve design, assembly, maintenance and repair issues before, the Air Force said. build a physical system.

The US Air Force report did not specify the cost of the project to build the aircraft. However, the report mentions that a mysterious jet under the project was tested in 2020, and it is still unclear whether the plane is manned or not.

“We have built and tested a new aircraft and broke all aircraft records,” said Will Roper, Assistant Secretary of the Air Force for US logistics and technology equipment procurement. fight. We are now ready to build the next generation aircraft in an unprecedented way. “

Some previous reports suggested that the NGAD program plane will have an artificial intelligence co-pilot, maybe even the ARTU system (artificial intelligence system built by algorithm to play chess. ).

The artificial intelligence system will act as a support for true pilots, but the weakness of AI systems lies in their logic, while actual military actions may not obey this logic. Human presence is then required to make a decision in unusual, non-standard situations.

It is known that from March 2018, the US Air Force Laboratory has released the image of the next generation F / X aircraft, showing that this aircraft will have a stealth design, eye-catching appearance with laser. High energy capable of cutting enemy aircraft in half.

This is also the main aircraft in the NGAD program, also known as the Penetration Jet. The future F / X aircraft is expected to have longer range and payload, as well as the ability to carry hypersonic weapons.

Under the NGAD program, the US Air Force advocates to exploit advanced capabilities of the new generation of aircraft such as air combat systems linked to fighters, drones and networking platforms. . With the aim of increasing air superiority, the F / X fighter program offers significantly enhanced stealth and works closely in coordination with the drone.

Until now, all information about the capabilities of the F / X is still a military secret. If the program progresses at a rapid rate through streamlined processes and uses current technology, the new generation fighter could join the US Air Force earlier than expected in 2030. .
