On the one hand, it is a very useful thing, as it protects the seats from dirt and preserves their appearance, since the fabric does not fade in the sun. On the other hand, under the covers you can't see the condition of the interior anyway, and most importantly: for whom should you protect it? For the next owner? Driving without covers is much more comfortable and cozy, so it's better to be careful and clean the interior in a timely manner than to spoil the appearance of the interior with covers.
In addition, most modern cars are equipped with side airbags, which are located in the sides of the seats. Using covers will result in improper operation of the airbags in the event of an accident or side impact and, as a result, possible injury to the driver and passengers.
