True, true... although I wonder if there might be some plumbing connected here; why upgrade MCU1 owners to MCU2 when an MCU3 is coming next year? At the moment, as far as we can tell, MCU2 only gives you a snappier browser (though I bet those Atari games will run like crap on it in v9)
AFAIK, it's not a new MCU which is coming next year, but a new AP computer. Those are two different computers.
In other words, if the current MCU Tesla is producing isn't updated before then, cars made starting sometimes next year will have MCU2 and AP3 instead of MCU2 and AP2.5 currently.
Purchasing FSD after the fact has always cost an additional $1,000. This is not new.
What MarkS22 meant is that Tesla recently increased the price of the FSD option by $1000 when bought after the original car purchase. Meaning it's now around $2000 more expensive than if you're buying it when ordering the car.
