And on top off that, some product manager at Mercedes might say they absolutely need let's say Atmos in the next release and ask the Tier 1 to implement it. The Tier 1 usually uses multiple Tier 2s. The Tier 2s say they need more memory, but that's not practical at all as you that hardware has been validated years ago and you don't just make incremental changes to automotive hardware, and there won't be a hardware refresh for another 4 years. It is in none of the tiers' interests to say they can't do it and lose out on a multi-year contract so they do the best possible job within the constraints.
