In order to follow the pedal habit of manual gear.

First of all, the pedal of an automatic car seems to be on the right when it leaves the factory. The purpose of this is to follow the driving habits of manual transmission cars, with the left foot controlling the clutch and the right foot controlling the brakes and parking doors.

Sit uncomfortably

When the brake pedal is turned to the right, the driver's comfort will be extremely low if he still steps on it with his left foot.

Talking about human life is: it's uncomfortable not to wear it. You sit there and you expect to sit there. An Mingyu also published a calculation paper "Research on the Layout Method of Floor-type Accelerator Roadboards of Fruit Cars" in the magazine of Automobile Times.

It says: the distance between the accelerator pedal and the right Xu plate is 35 to 45 mm, the distance between the curb plate and the accelerator pedal is 65 to 85 mm, and the distance between the brake pedal and the left Song plate is more than 200 mm.

If there is no brake on the left foot, it is better to drive with the right foot.

Hearing this, some friends will ask, "Then when I get on the bus, I usually move my left hand and have a rest.". Isn't it good? " In this case, the left foot brake becomes meaningless. On the internet, the driver's left foot brake is mainly to slow down, and at the same time, he can keep the speed by stepping on the accelerator, saving a little time for the right foot accelerator to change cars and reverse cars.

The left foot brake is not as good as the right foot control.

In addition, for most friends, the strength control of the left foot on the brakes is actually not as good as that of the right foot. Li Century of Harbin Normal University has a master's thesis, which I want to share with you, "Kinematics Research on Dominant Foot and Non-dominant Foot in Internal Kicking". For example, the size, speed and accuracy of the force exerted by the habitual foot are better than those of the unaccustomed foot.

If you are not used to braking with your left foot, it is easy to cause traffic accidents.

So generally speaking, people without special training are not used to braking with their left feet at all. Don't try, don't get angry, it's useless, don't try, if you don't control the strength of your left foot, it is likely to cause a traffic accident. Moreover, the design of the brake pedal is originally to the right, and stepping on the brake with the left foot will make us sit very uncomfortable and our legs are in a semi-suspended state.
