Honestly, players like Rivian and NIO shouldn't try to manufacture their own cars - they should contract that out to someone who knows what they're doing and already has the capital invested in production tooling (ex. Magna). Rivian/NIO & co. are best suited to design and engineering until they reach a market threshold where it actually makes sense to spin up a dedicated factory.
