Tesla just announced it was opening up their charge handle and charge port design for open use in the hopes it will be adopted as the standard. They’re even calling it the North American Charging Standard (NACS).

I sent an inquiry to Rivian to see if they had plans to offer the charge port as an option at some point or plan on adopting the NACS.
Being a current Tesla owner with home charging already in place, it would be nice not to have to buy another charger or use an adapter.
