So this article is about how Elon Musk, the boss of Tesla, laughed at Mary Barra, the boss of another car company called GM. She said her company would sell more electric cars than Tesla by 2025, but she was wrong. Right now, Tesla sells a lot more electric cars than GM in America. In fact, there's another car company from China called BYD that is also selling more electric cars than Tesla right now. Elon Musk thinks Chinese car companies are very good and could beat other car companies if they keep making better cars. Read from source...

1. The title is misleading and sensationalist. It implies that Elon Musk laughed at Mary Barra specifically for her 2021 pledge to catch Tesla in US EV sales by 2025. However, the article only mentions a recent laughing reaction from Musk to a video of Barra's statement from 2023. The actual context and reason for Musk's laughter is unclear and may be unrelated to the pledge itself.
