>Tesla has effectively incorporated Lane Keep Assist/Automatic Cruise Control into a single product called Autopilot that has vastly better software than other similar products.

Is it? This[1] implies that, contrary to what you say, most other manufacturers do offer equivalent features in equivalent luxury vehicles. Tesla might have gotten beaten many of them by a year or so, and might sell more Xs than Toyota sells high-trim Lexus's, but neither of those things really say anything about the quality of the driving technology. And from what I've seen, Tesla's isn't particularly spectacular.
