Mainly, but also the plug is smaller and easier to use than CCS1.

In Europe there’s a slightly improved CCS2 plug (without a latch sticking out), and all automakers including Tesla use CCS2. Superchargers aren’t dominant, and there’s no push to change the connector.

Thank you. It seems to be a no-brainer for other manufacturers to adopt to a common standard with additional benefits to their client base.

It's a welcome change, especially after years of proprietary solutions to shared issues.
