The past week has been bittersweet for Tesla. At the end: results of notable excellence. In the a very tense sectoral contextthe company that, a few days ago, stunned the competition with colossal sales, announced on January 25 record growth in almost all of its key figures in 2022.

Observers noted in particular a profit of 12.5 billion dollars (about 11.4 billion euros), as well as the placing on the market of 1.369 million cars, an increase of almost 50% compared to the previous year . In great trouble in recent months, especially due to Elon Musk’s Twitter escapades, As a result, Tesla’s stock price blushed.

On the face side, it’s a little more annoying, and this in the long run: the American publication Consumer Reportsa sort of transatlantic consumer bible whose tests and judgments are greatly respected and listened to, strikes at the heart of Tesla by dismantling what should be one of its strengths, the conduct of the service function, called Autopilot.

Second the long analysis of Consumer Reports published on January 25, this element that, from the beginning, made Tesla a technology company before an automaker, ended up falling far behind fierce competition –General Motors, Ford or Mercedes in particular, whose driver assistants have ended up placing autopilot in the soft underbelly of the group in the sector.

As Consumer Reports explains, these English-named systems “active driving assistance», or ADA, consist of the sum of two distinct capacities: the «adaptive cruise control(ACC), which allows the car to adjust its speed according to the environment, and “Lane Centering Assist”, which allows it to turn or change lanes in the event of a need or emergency.

Without hands (or head)

Consumer Reports tested twelve of these systems, all with unique characteristics. Now integrated into many vehicles placed on the market as well as on the road, however, they are far from being the same.

If they make up “a major advance that can help make driving easier and less stressful”, “they don’t allow a car to drive itself at all”, says Jake Fisher, the publication’s head of automotive testing. “Instead, they create a new kind of driving, working with your vehicle’s computers. When manufacturers get it right, they can make the road safer and driving easier. But if they do it wrong, it can be dangerous.

In this little game of delicate balance between automation and security, it is Ford and its BlueCruise systemGeneral Motors and its Super Cruisethen mercedes which have been most successful. Tesla, already at the forefront, however, falls in the standings, in which it aims for seventh place. One of the most important criteria on which Consumer Reports is based is the safety of the systems and how well they monitor the attention of the person behind the wheel, making sure that they are watching the road and are ready to intervene in an emergency.

These systems sometimes go through the installation of cameras that monitor the driver’s gaze, sensors capable of determining whether his hands are on the wheel and various warnings in the event of a violation of this obvious duty of attention. They are all the more essential as studies show that drivers place too much trust in their assisted or automatic driving system very quickly once they use it regularly, which poses serious road safety problems, specifies Consumer.Reports.

“We frequently observe situations in which the level of attention on the road is lower than that traditionally expected of a person behind the wheel, especially in light of the well-known limitations of these systems, which require the driver to always be ready to regain control safely and efficiently. quick”points out Pnina Gershon, of the Massachusetts Institute of Technology (MIT).

“Empowerment frees up resourcesadds. And unsurprisingly, drivers use these “freed up” resources for anything other than driving. What power You will play Elden ring on the vehicle console it becomes a point of saleas is the case with Tesla, it may not be the safest of ideas, nor are other older businesses.

As such, BlueCruise and Super Cruise are the most “serious”. They closely monitor the attitude of the person behind the wheel and do not give him the opportunity to wander for too long. Other systems, on the other hand, are much more forgiving, contenting themselves with a small, regular pressure on the steering wheel to consider all is well.

Tesla’s Autopilot, like Mercedes’, therefore, during testing, let the vehicles turn for thirty seconds without changing speed and without any intervention from the driver. That means, says Consumer Reports, that the car was able to travel more than half a mile without the driver concentrating on the road. “A rather risky situation”concludes the publication – and it is difficult not to abound.

The question is very delicate. On January 18, it was revealed by an engineer confided to Reuters news agency that Tesla’s first Autopilot demonstration video, released in 2016, it had been made up from start to finish.

The American agency responsible for road safety, the National Highway Traffic Safety Administration (NHTSA) has the manufacturer in its sights, given the oversold performance of its assisted or autonomous driving systems. Many procedures they are also ongoingparticularly following accidents seriously questioning the Autopilot much praised by Elon Musk.

Tesla, for its part, doesn’t seem to mind. A recent tweet thus attracted the attention of the federal authorities: in this, the boss said, replying to a user, that he thinks the ability to silence alerts in case of lack of attention.
