Yes, considering the questions raised, it is interesting the lack of knowledge about embedded systems, automotive market and their needs. However, I am not surprised at all. I know it since a way time before.
UPDATE
Just to explain the reason behind such - obvious - consideration above:
-
imagine to deal with a system that crashes 1 time ever 1 million runs. It would be nice to have it in smartphone market, it would be great. I wish SFOS would be so stable.
-
imagine to deliver 10 million cars and each of them is used on average 100 times per year. The number of runs is 1 billion and the number of fault is 1000 per year with 1:1M fault rate. Probably acceptable for an infotainment system.
However, (a) the fault rate 1:1M seems quite an utopia here and moreover the automotive industry requires (b) strict coding rules otherwise the whole system cannot be approved under that market standards.
Hence, even imagine to being able to achieve (a) and it would not be easy at all without paid skilled people who are supervising directly the community code production and made some tests before accepting external contributes, the (b) cannot be met by a community of hobbyist coders.
Even a professional developer, would not fit the with the strict requirements and therefore s/he would be just an hobbyist under this PoV. Without specific tools for inspecting and checking the code, I should consider myself an hobbyist coder in terms of automotive market.
Therefore, the SFOS community worth nothing in terms of automotive market because the coding requirements are too strict and certifications are required even if the fault ratio would be met. Moreover, this is just the peak of the iceberg.
There are many others aspect like SLA or long-term support, which cannot fit with a community in general and like this in particular. The bazaar model can do miracles but it is not a magic wand or a general solution for every kind of product or market.
The misconceptions about the bazaar model, about the community meaning, etc. are almost as wide as those about HR or quality vs performance or leadership mantras. Everyone wish to find the magic wand but many just put together words without even knowing the fundamentals behind (or they stick to obsoleted ideas).
A human history turning-point
The most hilarious fact is that while many people are trying to find the magic wand, a lot of others are arguing about who should use it, why and for what. The most iconic example about this attitude is the emerging debates about the AI, usually carried on by people that did not know a bit about that technology.
We are facing a quite interesting turning point in the human history: people who barely are able to use their smartphones (or still writing with CAPSLOCK on) are tricked by Internet “wonderland” to think that they can expressed their opinion about technology and they should be also listen because democracy… 
The next time you take a flight, tell the pilots that they should undergo for a democratic passengers community deliberation about how to drive the plane.
