According to the study, the sounds of the safety of your car actually worsen their safety

We all know someone who is too often discussed with Sound signals of your car. If you do not know anyone, you can be you. First of all, this happens with large drivers who drove cars that do not warn when there is a danger of a collision or exit from the marked lanes. It is logical that now these sound signals are annoying. But the reality is that even those who first get into the car may be surpassed Advanced driving assistance systems (ADA).

Realizes this situation, the team United States and Hong Kong Scientists He wanted to check whether this irritability caused by the ADA remains, or could go further. Could it be that car whistles even affect driving? If so, it would be completely counter -productive, right?

After the study, these scientists already have an answer, and this is really, the car whistles They negatively affect driving. Of course, before you run out, to deactivate them, you must continue to read it.

Not all ADA is equal

During this study, its authors divided the ADA into two types. On the one hand, those of Direct warning about riskThe field is the famous car whistles. For example, those of The risk of a collisionIt sounds alarm when there is another car or object at a short distance from the car, and in The output of the stripThe field in second place we find Informative adasThat they do not use sound signals to warn about the inevitable risk, but they start a warning about the signal that something can be difficult if it is not decided. For example, in this study Anxiety detecting blind pointsWith which light flashes when approaching the vehicle.

How do automobile sound signals affect drivers?

To check how the sounds of the car and the rest of the ADA affect the drivers, these scientists have collected Telematical data An important American car manufacturer. These data, from more than 195,000 cars, They support the anonymity of the drivers, but provide general data, which together can be very interesting. As for the vehicle, some of these data speed, acceleration and travel numberThe field on the other hand is offered general data, such as their age, gender or income level.

Soon, these data cannot tell us what a person’s conductivity is. But, in reality, if they are analyzed in detail, they can do this. For example, if The average speed of the car This is much higher than other similar vehicles, it is understood that the driver works too much. You cannot know what specific speed restriction, but it is clear that he should do this more than once. On the other hand, when measuring acceleration, slowdown is also measured. That is braking. If cars often stop and suddenly can be a sign of several reckless driving.

Comparing all these data with the presence or absence of ADA, something interesting was noticed. Begin 5 % more incidents from –THO speed and 6 % more sudden braking incidentsEvery day, compared to drivers that did not use ADAS. On the other hand, those who used only the detection of blind points 9 % fewer incidents from —the speed exceeding and almost 7 % less sharp incidents for brakingCompared to drivers that did not use ADAS.

Why all this?

The authors of this study believe that this is because different types of ADAS are launched Different brain chains. In the event of an inevitable danger of anxiety, they activate Cognitive system processing area 1associated with the processing of fast, automatic, intuitive answers and with slight efforts. On the contrary, the informative ADA activates The cognitive processing area of the system 2in which the answers Conscious, logical and reflectiveIn addition, they require more effort.

Drivers that are activated by system 1 usually trust, thinking that the car will solve problems in case they arrive. Therefore, they act without hesitation. They leave all the weight of responsibility in the ADA, and this makes them act with a large number impulsiveness, Moving greater speed and braking suddenly. On the other hand, with system 2, they act from thought and caution.

Do not stop using ADAS

Despite more impulsive driving, this study shows that the car whistles reduce collisions Compared to vehicles that do not carry any warnings. Therefore, even if they bring us a little crazy, this is not a very good idea to turn them off. Of course, for car manufacturers it would be quite good to look for a way to warn about risk without causing this impulsiveness. In the end, neuronauki are necessary for everything. Even make a car.
