Electric vehicle company Rivian is rolling out new software today. The lead feature is Enhanced Highway Assist, which controls steering, acceleration, and braking on compatible highways. It relies on an infrared camera in the rearview mirror to ensure that the driver is still paying attention to the road,

Enhanced Highway Assist is Level 2 autonomous tech that works on 135,000 miles of highway, with plans to expand off-highway over the next year.

Rivian is pushing a software update to its second-generation vehicles that includes a hands-free highway driving feature, the company said Tuesday. It was a notable announcement, considering the company has lagged behind its competitors in introducing partially automated driving features similar to Tesla’s Autopilot and General Motors’ Super Cruise.
