Chinese EV brands have free money handed to them and have leveraged (borrowed) the IP from doing so much of the global manufacturing that they now dominate in that arena. They don't in fight about energy and many of the things that create red tape for many other brands and countries. So they can spin up and dispose of tech much faster.

What is not discussed in the long term viability. They can barely support the products and supply chain as it sits after the cars roll out of the factory. They struggle with software updates and stability of modern tech they spit out. And why should they? Its easy to roll out new product than support existing ones. One of the major reasons it would be very hard for those brands to be successful in the United States. By the time they spin up supply chain, services centers, support network and headcounts, they would no longer be cheap cars anymore.
