The U.S. National Highway Traffic Safety Administration (NHTSA) is advancing efforts to regulate autonomous vehicles by proposing new lighting standards that would allow these vehicles to signal when operating without a human driver. The proposal recommends using cyan-colored lights that remain steadily illuminated on all sides of the vehicle, providing a clear visual cue that the vehicle is in autonomous mode. While not mandatory, this standardized approach aims to improve public awareness and safety as autonomous technologies become more widespread.

General Motors (GM) is making significant strides in automotive AI and autonomy, unveiling plans at its 2026 GM Forward event to revamp the computational systems of future vehicles. Starting with the 2028 Cadillac Escalade IQ, GM will introduce enhanced software capabilities, autonomous highway driving features permitting hands-free operation, and a new conversational AI assistant that will modernize its OnStar service. The company is also employing enterprise AI to halve its vehicle development cycles, positioning itself to better compete in the evolving mobility landscape.

In industry deals, electric automaker Rivian has acquired U.K.-based startup Third Dimension, which specializes in creating ultra-realistic 3D simulations from driving data to improve autonomous vehicle development. This move reflects the ongoing importance of simulation technology in closing the gap between virtual testing environments and real-world conditions. Simultaneously, reliable autonomous flying startup Reliable Robotics has secured $115 million in new funding, pushing its valuation over $1 billion and signaling robust investor interest in autonomous aviation technologies.

Other notable developments include Tesla and SpaceX boards forming committees to explore a potential merger amidst SpaceX’s booming AI business, Waymo expanding robotaxi services to Madrid and Las Vegas, and several startups and firms ramping up autonomous mobility projects globally. Additionally, GM is closing a Detroit-area battery assembly plant due to a lease expiration, unrelated to its EV strategies, while Google improves its Gemini AI assistant to personalize in-car experiences using connected services data.
