That’s true. The standard 10 years ago was the Chademo plug. Have any of you ever used it? It is HUGE. It’s like lifting up and plugging in an entire vacuum cleaner into the front of your car. The unveiling of Tesla’s supercharger plug 9 years ago was a game changer, and no one has yet equaled it.

It's true it was the standard on early Japanese electric stuff (the Leaf mainly), but it's a bit of an exaggeration to say Chademo was some kind of industry standard 10 years ago. Chademo itself is a creation of Japanese auto-makers plus Panasonic/TEPCO. The J1772 as well as of course Tesla's connector have been far, far more common sights in North America over the last 10 years. Western auto-makers have almost completely ignored Chademo altogether.

CCS is a bit larger a connector but not meaningfully so and is just as capable as the Tesla connector feature wise really - can support 350kw DC fast charging and automated payments etc. I'd be pretty happy if Tesla switched the cars over to a standard design like they've done on the Euro cars, assuming reasonable adapters were offered to existing owners.
