Tesla’s entry into the Chinese market via the Shanghai Gigafactory (2019) acted as a "catfish," forcing local Chinese "new forces" like NIO, XPeng, and Li Auto to lower prices and accelerate technological innovation.
Tesla made long-distance driving in EVs possible. Tesla made EV sexy, desirable. It catalyzed the Chinese EV industry. Nissan didn't remotely accomplish those things.
Like someone else said, people think in terms of a pre-Tesla and post-Tesla world. I don't know that there's a strong case against that framing.
