It isn't that it is superior in every single way, but it is the balance of features that hits a sweet spot, making other cars feel like they have noticeable bugs.
Things that I thought had been solved decades ago, things like how to make basic switchgear that doesn't feel like it's going to break off in my palm*. How to indicate a turn signal in the center of my field of vision rather than where non-essentials like HVAC normally go. How to let me change HVAC settings without feeling around on a touch screen. How to support Carplay like a base model Corolla. The most basic mitigations for NVH so highway speeds don't sound like a mouse sneaking cheese in a wind tunnel. How to make ACC intuitive rather than a song and dance of checking what color a piece of text is. All suddenly were suddenly lost.
* I guess now we know why the OG Model S needed Mercedes window switches.
I take a lot for granted about my M1 MBP.
And it all becomes noticeable when using anybody else's computer.
The screen, the speed, the battery life, the fan, the heat. Its all so... crippling on other people's machines.
