That map/calculation doesn't include that KIA will be manufacturing EVs at the West Point factory soon (the only plant in Georgia that is actually building cars to date).

Even though it's not a massive investment, it means that another big chunk of EVs will be made in Georgia.
In addition, there's the VW plant in Chattanooga, already making EVs, just outside of the state borders.
