carIt plays a very important role in the lives of all car owners. Everyone is familiar with cars, but how much do you know about cars?For example, I wondered a long time ago why the throttle andbrakeDon't put it aside?

Why don't you put the throttle and brakes aside?
Novice drivers are generally nervous, worrying that they may mistakenly use the accelerator as the brake and the brake as the accelerator, which may cause catastrophe. Why not put them aside and control them with the left and right feet respectively?
In fact, this design is for safety reasons.At the beginning, the car was manually geared and controlled by the left footclutch, The right foot controls the brake and throttle. Now the brake and throttle of the automatic transmission are also put together. On the one hand, it is to continue the driving habits of the drivers, and on the other hand, it is for the driver's quick response.
The brake and accelerator pedals are placed in front of the right foot with a certain gap in between, and the brake pedal is slightly higher than the accelerator pedal. The correct operation is to rotate left and r

The brake and accelerator pedals are placed in front of the right foot with a certain gap in between, and the brake pedal is slightly higher than the accelerator pedal. The correct operation is to rotate left and right with the right heel as the axis, and step on the pedal with the sole of the foot. For current cars, if the brake and accelerator are depressed at the same time, the trip computer ECU will also default to the brake priority. Therefore, the right foot to control the brake and throttle is the most scientific design.

Why is there a line on the outside of the car rearview mirror?
Car leftrearview mirrorThere is a line on the outside, do you know why? This is a double-curvature rear-view mirror. The outer part of the mirror is a convex mirror with a larger curvature, which can enlarge the viewing angle to reduce the blind spot of the driver and increase the field of view by about twice.
However, such a convex mirror will cause distortion, which affects the true distance between us and the car behind, so we retain most of the normal curvature of the mirror surface, and this line is a hint of the mirror surface transition.

How long is the life of car airbags?
Most people think that the car’sairbagIt is consistent with the life of the entire vehicle, but in fact the life of the airbag is not that long. If the airbag has not been detonated and replaced in 8 to 10 years, its quality and performance will be difficult to guarantee.
If the airbag keeps flashing while the vehicle is starting or driving, it means that there is a malfunction and you need to go to the 4S store to check or replace it in time.

There is also an "escape pod" in the car
There is also an "escape pod" in the car. Do you know that?As we all know, car doors, car windows, carsSkylightThey are all escape routes. But in case of an emergency, the doors and windows cannot be opened, the trunk is actually an escape route.
You can put the second rowSeatPut it down, drill into the trunk, find the opening of the trunkswitch, And escaped smoothly through the trunk.

Why are the wheels of passenger cars and trucks convex and concave?
In fact, for busesWheel hubThe front and back are convex facing outwards and concave facing inward.The concave part enables the installation of brakes andsteering systemThe space is larger, which is why the concave side faces inward.
As for what the rear wheel looks concave, this is the perspective effect.Because in order to facilitate steering, only one front wheel is installedtire, And two rear wheels are installed to carry the weight.tireIt is fixed with convex and inner tires, so it is visually concave.
