Wow, that's a huge undertaking, but awesome.
The problem in my world is user level abstraction bloat killing all performance gains at the embedded software inside the hardware & the hardware itself.
I would never dream of trying to write an operating system let alone embed that operating system in special made custom ASIC chips, they
will need a team of good people to do that- I'm talking way up there in talent which I'm sure they can afford if they want to.
I don't know how Tesla does it but if they are running their own bare bones linux system or their own custom fork I can see that working ok(or other bare bones OS).
Proven and supported kernels and interface forward toward the user level and work well backward interfacing with the embedded software at the hardware level.
The recipe for speed is not always a faster processor or more cores in the processor or wider bit data bus but that's the approach I've been seeing for many years
because it is so much more work to gut everything and start over- thus the layers and layers of processor clock instruction gobbling abstraction and bloat. haha

Yep exactly.

That is rapidly changing. It's the precise reason VW, BMW, and Mercedes amongst others all announced their next-gen vehicles are all going to have manufacturer-maintained operating systems. As Mercedes says, "Based on a purpose-built chip-to-cloud architecture, MB.OS benefits from full access to all vehicle domains: infotainment, automated driving, body & comfort, driving & charging."

Tesla is also famous for being delayed with everything that they do. Such a delay is quite rare for the Germans, which is why VW's CARIAD disaster has been so widely publicized. BMW and Mercedes are right on schedule, so stay tuned. Next-gen CLA debuts MB.OS in 2024 (hits road in early 2025), BMW not until their Neue Klasse platform cars debut at the end of 2025. I have very serious doubts that they'll be deviating from that schedule.

Promises promises.

you are not the only one. 
ok, just about everything. tell us anything elon promised (besides a promise like the day before) that was delivered when he said it would be.

I think I mentioned the state of VW's software issues twice already. And yes, I exaggerated by saying everything. But I can't tell if you're here to have a serious conversation given all you've done is cite VW being behind which we've already talked about. No matter which way you slice it, Tesla has a well-deserved reputation for talking about features and product being delivered on timelines that have not matched reality. This does not require debate.

Now tell me what auto maker has FSD that can drive anywhere, structural battery, mega castings, dry process battery cells, 48 low volt architecture, OTA updates on every mass production car they've built from day 1. Context matters. But if some people only want to bang the same drum, Elon "promised" X have at it.
The stupid thing to me is it's not like Tesla makes forward looking statements, then does nothing about it. They pour blood and treasure into making it happen unlike so many other auto makers that promise the moon and do sweet blank all about it.
