The correlation is that both installation steps are happening in the same assembly line, in the same conditions, by the same workers/robots. Panel installation is a solved problem. Brake installation is a solved problem. Electronics installation is a solved problem. Except one of those solved problems very clearly isn't "solved." This is something that stops assembly lines in other manufacturers. That it doesn't with Tesla signals that other assembly-line-stopping issues may also be ignored.
