Rivian's software chief has discussed the company's potential partnership with Volkswagen, with reports suggesting the two are in talks to widen their tech partnership or have already launched a joint venture. The nature and status of the partnership are unclear, with some outlets reporting progress and others indicating setbacks. Rivian's software approach is also being highlighted, with a focus on voice-controlled and hands-free systems, potentially reducing the need for traditional interfaces like buttons or third-party services.
