The Autonomy+ offering will be priced at $2,500 as a one-time, up-front purchase or is available for $49.99 per month to start. By comparison, competitor Tesla offers its premium FSD (Supervised) option for $8,000 up front or a $99 per month fee. Shares of the company were off roughly 3% during the hourlong event, and fell further as OpenAI made its own AI announcement Thursday, revealing its most advanced model yet. “AI is enabling us to create technology and customer experiences at a rate that is completely different from what we’ve seen in the past,” Rivian founder and CEO RJ Scaringe said during the event.Company executives said in a statement that a near-future software update will include a “Universal Hands-Free,” capability, enabling Rivian customers “hands-free driving” on more than 3.5 million miles of roads in North America, covering the vast majority of marked roads in the U.S.Scaringe said the new advanced driver-assistance system will continue to improve as more miles are driven, through reinforced learning. He did not disclose a timeframe for the full autonomy or potential robotaxi fleet.Unlike its primary competitor, Tesla, Rivian said it intends to use lidar, or light detection and ranging, systems and radar sensors in its forthcoming R2 cars to enable “level 4,” or fully automated driving, as defined by SAE Levels of Driving Automation.A passenger can sleep in the back seat in a level 4 self-driving car while it carries them to their destination in normal traffic and weather conditions. Waymo, the Alphabet-owned robotaxi leader in the U.S., considers its vehicles level 4.

Tesla and General Motors are working on their own proprietary driverless systems, while Honda, Lucid and Nissan have partnered with venture-backed autonomous vehicle tech startups (Helm.AI, Nuro and Wayve, respectively) to develop similar systems with a range of different technical approaches.[embedded content]Rivian and Tesla stock’s since Rivian went public.
