We will find out how software locked the SR battery is at the beginning of June. Why the beginning of June? That's the third month of the next financial quarter, when Tesla will start scheming how to get more money out of us to make the stockholders happy, once again.
So if Tesla makes an announcement with words to this effect, you know it was software locked, possibly even a locked MR battery:
"Hey all you cheap asses who penny pinched your way into a base 3 and put the companies' financial health at risk --- would you like some more SPEED? Would you like some more RANGE? Well, for just A FEW DOLLARS MORE, how does 264 miles of range and 5.2 0-60 and 140 mph top speed grab you? Only $2500 on your credit card!!!".
We'll see.....
