Rage erupts in a Tesla parking lot

The video begins with two women arguing in a Tesla dealer parking lot. They sound like they are speaking Chinese. One woman is sitting in the driver's seat with the door open. The other is standing next to the driver. After a few seconds, the standing woman starts to hit the seated driver. The driver gets out of her car and they both hit each other for a bit. Then the driver returns to her car. The video stops and starts at a new point in time to show the driver nearly running over the other woman. The woman who was almost run over then gets in her car and rams the other driver's car, making a loud crunch. I wonder what the fight was about. They should be happy to have such nice cars.
