Automobile patent value

Upstairs, the appearance patent is 10 year. I don't know if there are any special regulations in the automobile industry, but the fact is that after five years of making the appearance of your car, do you think others will adopt you without designing a new appearance? Your car is on the market. It is estimated that no one will be idle to make different labels for the same car, which will only ruin their own brand. If there is such a statement, I think it is more for the convenience of some small brands with no design ability or strong design ability.
