The animation of automobile rear windshield is set by electronic screen. This kind of cartoon is actually very simple. Now, if you want to post that animation, you can also ask him to draw it for you directly, or you can search online, buy all kinds of cartoons you like, take a shower after you come back and let him wash your car. You can post it yourself or ask them to post it for you, but there must be a charge for others to post it.
