A friend said that before I bought a car, I always thought that the function of cruise control was very good, anyway, I didn't need anyone to drive when I turned it on, and it was very tall and convenient and not tired, but after buying a car, I used it a few times and never used it again. In fact, this is not only the case for my friends, but also for myself, and some people have never even used the cruise control function. Why is this happening? Today, Xiao Li will explain to you clearly at one time, like the collection, and dry goods.
The most fundamental reason why I rarely use the cruise control function is that it is not smart enough, after turning on the cruise control function, you don't need to step on the accelerator, theoretically the right foot can rest, but the reality is that if you want to drive safer, the right foot will be more tired. Because you have to take care of the brake with your right foot, and you have to prevent your right foot from unknowingly stepping on the brake.
Usually, when we drive at high speed, the right foot is basically diagonally stepped on the accelerator pedal, even when there is no need to refuel, the accelerator pedal can also support the natural weight of the right foot, and only put the right foot on the brake pedal when braking. I believe that in addition to novices and urban road conditions, there is no old driver who will put his right foot on the brake pedal when driving on the highway without refueling, at least I have never had such a habit, I am used to letting my right foot naturally press on the accelerator pedal when I don't refuel, so that the right foot is not tired, and the car will not accelerate randomly.
But if you press your right foot on the brake pedal naturally, you will find that the spontaneous combustion weight of your right foot will press down the brake pedal a little, we don't know if the distance of the pressure will cause the brake pads to drag the brake, but at high speed, you will find that the right foot is just on the brake pedal not long after you have to move over the gas pedal, you will find that you will make the right foot very busy moving back and forth, but more tired. And I am such a thin person whose right foot can be pressed down on the brake pedal, some people are heavier, and the weight of the right foot will directly make the brake system work. So what does this have to do with the cruise control function?
If you put it on the accelerator pedal, as long as you encounter a little bump, your right foot will press down the accelerator and release the cruise control. If you rest on the floor, you may not have time to apply the brakes with your right foot in an emergency, or even use the accelerator as a brake. It is safest to ride on the brake pedal, but I am always worried that my right foot will press down the brake and drag the brake to drive, so I will subconsciously gently lift my right foot, so that you will find that the posture of the right foot lifting a little bit is very tiring, and it is better to put it directly on the accelerator. And, cruise control has a fatal drawback.
When I was in Wuhu, Anhui Province, I chatted with an old taxi driver about this problem, and he said that this function is a chicken rib, and it is easy to be distracted on the highway because of this function if you can't rest your right foot. Once distracted on the highway, it is easy to get out of danger, and when approaching the car in front, it will not automatically brake, and old drivers generally do not like to use it. However, adaptive cruise control is much better, and with lane departure assist and lane departure warning, it is safer to drive at high speeds than cruise at a fixed speed.
Some people have seen those videos on the Internet, saying that the cruise control cannot be lifted after it is turned on, and it is useless to step on the brakes, which makes it very dangerous for the vehicle to go all the way, and they are scared and worried about whether their car will have this kind of problem. Although I knew it was a matter of probability, if it appeared, it would be nine deaths, and I was scared, so I never dared to use this function. In fact, the function of cruise control, if you use it a few times, you will find that it is actually really not easy to use, not smart enough and may even have problems.
In general, the function of cruise control is really not a very easy to use function, and the manufacturer is also aware of the problem of this function, so it has been upgraded to adaptive cruise, and now this function is only available in low-profile models, and high-configuration models are basically adaptive cruise.
