Li Auto's Halo OS aims to challenge the closed-source AUTOSAR and is expected to save the automotive industry up to RMB 20 billion in investment each year.

I use Syncthing for this. This is peer-to-peer syncing so you don't need a cloud service in between. Works well on all platforms.
I also use filen for encrypted cloud storage and nextcloud for mulitfunctional cloud storage and can work fine as well but nextcloud is much more complex and CPU intensive so the pi might struggle with certain operations as it retains much more information (databases and such).
Rpi4 can work with Syncthing (tested) because it works as a local webserver so you only need an OS with a browser (or do it all in the terminal). Doesn't really matter which OS you use, most will work so Raspberry Pi OS for the pi is fine. Syncthing is in the official repo of Fedora and Opensuse.
That domain isn't in use (yet?)
If reviews are good i'd definitely try it as an upgrade to my trusty Logitech Ergo M575
I know at least one kind that had a high degree of aluminium in it. But you also have cheaper kinds that dont have that.
What about heatsink thermal paste?

This looks way to break with chip restrictions bound by the leading software package AUTOSAR. But I think, like all FOSS, will benefit everyone in the end.

Did this using iodéOS which is a LineageOS distro with more degoogling and os level adblock and filtering build in. Works very well and has been stable for about the 4 heads that its running on my FP4.
Check out iode.tech as well. Like /e/OS, also a lineage OS variant but with build in firewall which you can customize (or turn off). Fast security updates and great default informed FOSS apps (unlike /e/OS).
The combining of subscriptions i s exactly why I like liftoff as well. Used a couple other clients, but Liftoff seemed the most stable and easy for me.
