Remember that factories for CT and 4680 aren't even finished yet. Elon gets criticism for unrealistic time lines and you expect him to get into the details about production.. supply chain interruptions and inflation and ramping to production.. too many variables. You sound like teenagers...
I think the optional choice is for Tesla to open their one and only Cybertruck Texas dealership at the Austin factory. And Service Centers everywhere in Texas. Win-Win .

Idea to consider.. build charging port on rear of cybertrailer so it can charge cybertruck without unhitching the cybertrailer. Only requires cybertruck with attached cybertrailer to backup to supercharger. ??
