We're off the rails here but on your second point:Tesla may never add things more common on other brands. Apple doesn’t add things that Android can do and vice versa.
Like a fingerprint unlock (Android did it first), facial recognition unlock (ditto Android), front camera notch (Android), wireless charging (Nokia IIRC then Android phones/Qi standards)? Apple has of course iterated and adopted features and designs popularized elsewhere, the inverse is also true.
If Tesla aren't watching and learning from competitors, like everyone else, their lunch will eventually get packed by those competitors.
