1. Why is the engine cover soft?
The first is to protect the driver. Assuming that your engine cover is hard enough, the engine cover may be inserted directly into the cab when hitting an object. Can you imagine the consequences? The second is to protect pedestrians. Generally, when hitting a pedestrian , the pedestrian's feet will be in the air, and the upper body will directly hit the engine cover. This design can reduce the damage to pedestrians. Finally, the engine cover is made thinner to facilitate dry warp quantification. Even though the engine cover is relatively soft, this does not affect the vehicle's collision performance at all, and car owners do not need to worry about safety issues.
2. Why is the brake pedal higher than the accelerator pedal?
Why do the brakes of the cars we usually drive have to be higher? In fact, this is to allow the driver to better distinguish between the accelerator and the brake. There is a very important thing when driving called "feet feel". First of all, the pedal areas of accelerator and brake are different. , and the longitudinal height is more important. When you step on the brake, it will give you a completely different sense of depth than the accelerator. This will help distinguish the two and prevent confusion.
3. Why aren't the spare tires full-size?
Compared with normal tires, spare tires are smaller and ugly. They are designed to make car owners feel uncomfortable. Moreover, non-full-size spare tires have a speed limit. If you cannot drive fast, car owners will want to find a repair shop quickly. Repairing and replacing it, plus the fact that the non-full-size spare tire takes up less space in the trunk, can also reduce costs for the manufacturer.
