Behind the failure of mercedes benz c-class cruise control, how can Mercedes-Benz turn off the function from the background after sale?

Today, the circle of friends was screened by the news that a mercedes benz c-class cruise fault caused the owner to run at a high speed 100 kilometers. Here's the general thing. The Mercedes-Benz C200L car driven by Mr. Xue lost control after cruising at a constant speed, so it was impossible to slow down and stop. He can only run at the speed of 120 km/h, and his life is at stake! Fortunately, Mercedes-Benz C200L car stopped safely after losing control for nearly an hour, with the emergency rescue of high-speed traffic police in Henan and Shaanxi provinces and the full operation of Mercedes-Benz after-sales.

While everyone was glad that the owner was not injured, many netizens marveled at how Mercedes-Benz turned off the constant-speed endurance function from the background after sale. Mercedes benz c-class car networking seems to have no such function. Even some internet car manufacturers have no such operation in the background. Sure enough, it was not long before the truth was exposed. It turns out that it is not the function of Mercedes-Benz after-sales shutdown, but the function of cruise control can be resumed when the owner opens the door and loosens the seat belt.

Unlocking the seat belt door will slow down or even turn off the fire, which is a safety logic. Many car companies are involved in the functional design, which is normal, so don't speculate too much. The background operation of Mercedes-Benz is purely an oolong joke, and there is no background technology of car networking in mercedes benz c.
