This was mentioned by Elon in the recent conference call, but has been a tidbit that I have not seen much discussion about (unless I have somehow missed it). SO. What upgrade could significantly impact the entire fleet?? Could this just be the autonomy features finally being activated? Maybe, but that really does not impact the majority of the fleet, right? Could it just be an increase in the top speed, or maybe another acceleration upgrade? If so, I don't know if this is really such a big deal, and Elon sounded excited about it. Any other ideas? My dream - that all mirror stalks were secretly outfitted and wired, from the very beginning, with the hardware necessary to mount rear view cameras and take the mirrors off, and all Tesla is waiting for is the final NHTSA approval. That would be incredible, but so so unlikely.
