Waymo, the trailblazer in autonomous driving technology, is exploring the cutting edge by experimenting with generative artificial intelligence to make its self-driving cars safer than ever. Unlike some competitors, such as Tesla, which rely mainly on cameras for navigation, Waymo insists that radar and LiDAR sensors are essential for safely operating under all weather and traffic conditions.
Why Radar and LiDAR Still Matter
According to Srikanth Thirumalai, Waymo’s vice president of onboard engineering, the company’s vast experience from millions of driverless miles has shown that diverse data sources provide an “additional safety net.” Unlike camera-only systems, Waymo’s LiDAR can detect human movement or unexpected obstacles that cameras might miss—such as pedestrians poised to step into traffic or a vehicle maneuvering around a stopped bus.
This layered sensing approach has allowed Waymo to scale its robotaxi services to five cities by mid-2025, accumulating over 100 million miles with remarkable safety results. While Tesla touts a vision-only approach to keep costs low and simplify sensor suites, Waymo maintains that a full sensor array including LiDAR and radar is vital for consistent, safe autonomous driving.
Where Generative AI Fits In
Waymo is actively researching how to integrate generative AI models—specifically Google’s Gemini—into their system to further enhance perception and decision-making. The company has developed a multimodal AI called EMMA (End-to-end Multimodal Model for Autonomous driving), which combines input from various sensors to improve object detection and navigational planning.
Though promising, generative AI models like EMMA currently face challenges: they cannot yet fully replace LiDAR and radar, processing fewer image frames and lacking fusion with laser sensor data. Waymo executives acknowledge much work remains to simplify and perfect these AI integrations for real-world driving.
The Road Ahead
Waymo’s experiments represent a key step toward more intelligent and adaptive self-driving fleets. By blending trusted sensor tech with next-gen AI, Waymo aims to build a safer, more reliable autonomous future—distinctly different from rivals who bet solely on camera vision.
The company remains open to innovation but underscores that safety is paramount. With millions of autonomous miles logged and constant research underway, Waymo is driving the industry toward more robust, AI-enhanced vehicle autonomy for everyone on the road.
