Answer: To clarify, more that a company should stick to their core competencies unless there's a drastic need or opening in the market that could be filled (and to build a new competency).
In this particular case, there's nothing particularly unique that Rivian is doing with their Infotainment system that couldn't already be handled by an incumbent in the space, (Android Automotive, QNX, etc.) especially given how modular the systems themselves are.
As State Farm says, "We know a thing or two because we've seen a thing or two".
Rivian thinks of itself as a software company. The first thing you sign when you go to buy a vehicle is a software copyright notice IIRC. The first thing in the owner's manual is a notice that the software copyrights and intellectual property belong to Rivian, etc etc.
Observation: "[if you write buggy software], there's reason for you to get an off the shelf option"
Question: Are you saying if they used Android Automotive this could never have happened?
