Three car cold knowledge that most old drivers don't know.

Now many consumers can be said to know more and more about cars. They not only know the brand of the car like the palm of their hand, but also know the engine displacement, gearbox and chassis suspension like the palm of their hand, but I believe many people really don't understand the cold knowledge of the car.

Here are three things that most old drivers don't know about automobile coldness. Do you know anything?

Number one: Do you know why the accelerator and brake are not put aside?

Now there are more and more female drivers, and all kinds of wonderful driving problems are often seen in online news. What we often see is that "the accelerator of a female driver acts as a brake, causing ...". Why can't you put the brakes and throttle aside?

The development of automobile has a history of 100 years, and all automobile structures are basically mature, so is the objective mechanical design. The position of the brake and throttle has always followed the tradition and is still in use today. The designer should have thought about this problem repeatedly and finally came up with this plan.

If you brake on the left and throttle on the right in automatic transmission, can your feet cooperate well at the critical moment? Can you promise to release the accelerator while stepping on the brake? How to avoid "throttle as brake"? I think we should stick to the principle of "braking first".

I have never experienced such a thing since I first drove, and I still don't understand why I stepped on it wrong. This is completely two kinds of feelings, just like wiping your nose won't rub on PP. In a word, it's not that others' designs are unreasonable, but that you are at fault.

The second one: there is also an "escape pod" in the car! Do you know that?/You know what? Do you know that?/You know what?

If you encounter an emergency, such as driving into the water, you can open the skylight to escape quickly. If the skylight is powered off, you can escape from the back seat of the car at this time. Generally, there is an emergency escape switch at the back of the car, and each model is different. You can open it in the back row.

I think the most important thing is that many vehicles can't open the door because of deformation, so they can return from the trunk at this time.

Third: Why are the wheels of passenger cars and trucks made in scraggy?

Everyone has seen the hub of a bus or truck, and you will find that the concave and convex surfaces of the wheels are different. The front wheel is convex and the rear wheel is concave. In fact, the rear wheel is composed of two tires. All we see is a kind of wheel hub. If we win, it will be exactly the same! Of course, winning a combined rear wheel is quite dangerous.
