Note: “tesla recalls” == “tesla pushes OTA software update (just like any regular OTA update)”
I think at some point the absurdity of the numbers (now it's 2M, soon it'll be 10M, 50M, ...) will become so great that NHTSA will stop calling this a "recall", and then this term will no longer be usable for clickbait article titles. Absurdity because it'll get harder and harder to imagine how a company might bring in millions and millions of vehicles in for service repeatedly, from a logistics and cost perspective,…
But imagine one of those massive castings developing cracks and needing some reinforcements welded on in the field, or really any part. FEA is probably the most important tech that Tesla is dependent on.
