In what ways are they ahead though besides price. A new iPhone has more battery, a camera with more MP, a faster chip etc. These cars have the same or shorter range then they’re competitors, same or slower acceleration, same cargo space, charging speed etc. just cheaper because of the reasons mentioned above.
When Japanese cars started taking off in the 70s it was because they had way better fuel economy and build quality then anything Detroit was putting out at the time, they were better at those fields. I don’t see any field where these cars are better at besides price.
