Yes, the car needs a shock absorber.
The effect of the shock absorber of the car is to avoid bumpy phenomena in the process of driving. In fact, the principle of automobile shock absorbers is simple. When the spring of the car shock absorber occurs, the oil in the car is sprayed into the small hole. This limits the bump of the car, and this design is very clever. Different cars have different shock absorbing properties, mainly due to different aperture size. Therefore, the most important role of the car shock absorber is to avoid violent vibrations.
