How did OP even know that an accelerometer exists in the first place?
How to access it is undocumented.
While officially undocumented, people figured out how to access it back then, with novel uses like smacking your MacBook to change spaces (virtual desktops) or swinging the Mac around to make lightsaber noises.

(I should know, I was in university back then and swung my Mac around like an idiot, lol.)
On the first Retina MacBook Pro 15" in 2012, and moving forward with all MacBooks that were SSD-only, they removed the SMS as it was not needed.
To my knowledge, this is the first time we're hearing that Apple Silicon machines have an accelerometer on the SoC, officially or otherwise. It's also certainly not branded or marketed as the SMS was. (https://support.apple.com/en-us/100871)
Happy to be corrected on this!
They could not figure out what it was for.
Ars Technica commenters at the time believed it was to record drops so Apple repair teams could rebuff requests :)
“Vehicle Motion Cues
Vehicle Motion Cues may help reduce vehicle motion sickness while using a Mac and riding as a passenger in a car or other on-road vehicle.
To customize Vehicle Motion cues, click Customize Appearance, then set any of the following options:
- Pattern: Select Regular for a stable and predictable pattern of onscreen dots, or Dynamic for a more engaging visual experience.
- Color: Select a color of onscreen dots. Color saturation will automatically adjust to maintain contrast with the content behind each dot.
- Larger dots: Turn on Large dots to increase the size of the dots that appear onscreen.
- More dots: Turn on More dots to increase the number of dots that appear onscreen.
Note: This option is available on Mac laptop computers. It’s not available on MacBook Air (M1) or 13-inch MacBook Pro (M1) or earlier.”
The one thought that comes to mind is this: "Your warranty claim was denied because we determined that the laptop was subjected to a sudden shock."
maybe apple was preparing for "carrying-around laptop experience"?
and there is Mac Catalyst (iOS on Mac) and Mac support.
what am I missing ? that this uses a raw stream ?
Sorry to disappoint. I’m working in the human rights space, with dozens of real world experiences by people I work with. I got raided once myself. They were unable to locate any computer on my premises. They however took my phone and a couple of encrypted hard drives for forensic analysis. They asked for the device PIN, which I did not provide. A court later ruled the raid and seizure and temporary confinement illegal. I did not reuse the returned phone. They didn’t pay for the replacement, or the lawyer.
