GM Begins Supervised Public-Road Testing of Next-Gen Autonomous Tech

General Motors has begun supervised public-road testing of its next-generation automated driving technology, marking a key milestone in its roadmap toward hands-free and eventually eyes-off driving. The testing phase represents a shift from data collection to real-world validation as GM advances its autonomous capabilities.

The update was shared via a GM Engineering blog post, outlining the company’s latest progress in autonomous system development.

GM transitions to real-world testing for next-gen autonomy

GM said its new automated driving system has entered supervised testing on limited-access highways in California and Michigan, with plans to scale to more than 200 development vehicles.

Each vehicle will operate with a trained test driver behind the wheel, ready to take control if needed, as the system is evaluated in live traffic environments.

The company described this phase as a transition from manual data collection to active system testing, building on a dataset of more than one million miles driven across 34 states.

GM said insights from this testing will feed directly back into its development cycle, improving the system’s AI models and overall performance.

Data, simulation, and new architecture support 2028 rollout

GM is targeting the launch of eyes-off driving technology in 2028, starting with the Cadillac Escalade IQ before expanding to additional gasoline and electric models.

The system will be powered by GM’s centralized computing architecture, which consolidates vehicle functions and allows the technology to scale across multiple models without requiring a full redesign.

The company is leveraging a large data foundation, including more than 800 million miles from Super Cruise and over five million autonomous miles logged by Cruise in complex urban environments.

To accelerate development, GM also uses simulation tools capable of replicating around 100 years of driving scenarios per day, complementing real-world testing.

GM said the supervised testing phase is a critical step toward delivering safe, scalable autonomous driving systems and building public trust as deployment approaches.
