At CES 2023, the Munro team explored three bold visions for the future of autonomous vehicle technology. These included high-speed racing, urban robotaxis, and heavy-duty mining. Despite their differences, each application shared a clear message: autonomous mobility has arrived. It’s no longer a concept — it’s becoming essential for performance, efficiency, and safety.
In this article, we examine how these three sectors reveal the growing capabilities and real-world readiness of self-driving systems.
Indy Autonomous Challenge: Racing Toward AI Precision
The Indy Autonomous Challenge (IAC) has moved beyond novelty. It now serves as a proving ground for AI-driven race cars, with speeds topping 130 mph. At Las Vegas Motor Speedway, Paul Mitchell — President of the IAC — joined Munro trackside to share how far the competition has come and where it’s headed next.
What began as a DARPA-inspired prize competition has grown into a platform where university teams from around the world develop autonomous driving software for real race cars. These aren’t scaled-down testbeds. The cars are full-size, high-speed Indy Lights chassis, originally designed for human drivers to race at 190–200 mph. Now, they’re equipped with complete ADAS stacks replacing the human in the cockpit.
The chassis and mechanical setup are standardized. This levels the playing field and shifts the entire competitive focus to software — the AI driver. Teams cannot alter downforce, suspension tuning, or engine calibration. The only differentiator is code.
Progress has been dramatic. Advanced teams now demonstrate overtaking and crash avoidance behavior that rivals human intuition. As speeds push beyond 130 mph, the AI must manage real aerodynamic instability and split-second decision-making. Teams from the Technical University of Munich and Polytechnic of Milan (in partnership with University of Alabama) consistently top the leaderboard, with strong competition from teams based in Abu Dhabi, Korea, and the U.S.
While the current focus remains on oval tracks — ideal for controlled, high-speed testing — Mitchell confirmed that road courses are on the horizon. Announcements are expected soon, signaling a shift toward more complex and realistic driving environments. Yet even as AI performance accelerates, human-level decision-making under pressure remains a decade away.
Zoox: Designing Robotaxis from the Ground Up
On the urban mobility side, Zoox is taking a radically different approach. Rather than retrofitting autonomous systems into existing cars, Zoox has engineered its driverless vehicle from scratch. Director of Studio, Chris Stoffel, joined the Munro crew at CES to explain the company’s vision for a purpose-built robotaxi.
Zoox’s vehicle is fully symmetrical — front and back — allowing bidirectional movement and minimizing turnaround time in dense urban environments. The design incorporates four identical sensor pods on each corner, combining lidar, radar (short and long wave), and cameras. This multi-modal sensor suite is essential for robust autonomous perception across varied lighting, weather, and traffic conditions.
The interior reflects a similar ground-up reimagining. With communal seating, minimal controls, and an emphasis on calm and simplicity, Zoox treats its cabin like a mobile lounge — not a car. The goal is user focus and comfort. Riders can work, sleep, or socialize without distraction. There are no buttons to press or mirrors to adjust. You get in, press “Go,” and the vehicle does the rest.
Zoox’s material choices reflect its future-focused design strategy. Engineers built the body from carbon fiber reinforced polymer (CFRP) to reduce weight and boost durability. They also chose a symmetrical architecture — front and rear — to simplify service, standardize parts, and maximize uptime. These decisions aren’t just clever; they’re critical for scaling a reliable and profitable robotaxi fleet.
Zoox plans to operate its own mobility service instead of licensing its technology. Its Level 3 test fleet has already logged significant mileage on public roads. Now, the production model is fully homologated and ready for real-world deployment. As pilot programs roll out, Zoox will focus on one core promise: a consistent rider experience. Whether you’re in Las Vegas or Michigan, the interface, comfort, and confidence should feel exactly the same.
Caterpillar: Heavy-Duty Autonomy for Mining Efficiency
Not all autonomous vehicles carry passengers. At CES 2023, Caterpillar demonstrated its latest developments in self-driving mining trucks — a segment where automation already delivers operational efficiency and safety benefits.
Munro joined Caterpillar’s representative to explore the company’s 100-ton quarry truck, fully equipped for autonomous operation. Although the vehicle still includes a traditional cab — due to operational flexibility requirements — the heart of its intelligence lies in a hardened, weatherproofed ADAS system.
Unlike urban vehicles that rely on Google Maps or 5G connectivity, Caterpillar’s mining trucks operate in extreme environments — from the oil sands of Canada to the dusty pits of Western Australia. These trucks require high-precision GPS, robust lidar and radar fusion, and terrain-adaptive autonomy that functions amid snow, fog, and iron dust.
Caterpillar owns the intellectual property for its mining-grade lidar and has spent a decade training the system to interpret environmental obscurants that would typically confuse autonomous sensors. Combined with radar for long-range perception, the trucks now exhibit impressive resilience. Importantly, the system is fully autonomous — decisions about routing, load assignments, and path planning are made by the truck in coordination with a centralized assignment engine. There’s no remote joystick operator in sight.
One standout feature sets Caterpillar trucks apart: they can autonomously detect the type of material loaded into their beds. Based on that data, the trucks adjust their routes in real time to meet destination requirements — whether it’s a crusher, dump site, or shorter queue. While the cab still supports occasional manual operation, a simple switch lets operators toggle between autonomous and human-driven modes. This flexibility is crucial for maintaining uptime during field service and repairs.
Looking Ahead: Battery Electrification and Charging Innovations
Autonomy isn’t the only future-facing trend in heavy equipment. Caterpillar also unveiled its prototype 250-ton battery-electric mining truck. While battery capacity remains a limiting factor for ultra-heavy-duty vehicles, Caterpillar is exploring dynamic line charging — a system that recharges vehicles while in motion, especially downhill. The concept is akin to regenerative braking on electric cars but scaled up dramatically.
This regenerative approach, combined with renewable power sources like hydroelectric dams (already in use by mining giants such as Vale in Brazil), could help eliminate diesel entirely from some operations. That’s a win not just for emissions but for logistics — fuel transport is one of the biggest challenges in remote mining regions.
Final Thoughts: A Cross-Sector Leap Toward Smarter Mobility
From the racetrack to the rideshare fleet to the quarry pit, CES 2023 showcased autonomous vehicle innovation at every scale. What connects these use cases isn’t just technology — it’s a focus on lean engineering, safety, repeatability, and end-user experience.
The Indy Autonomous Challenge proves that software-defined performance can rival human instinct. Zoox shows that thoughtful, clean-sheet design can redefine how people move through cities. And Caterpillar demonstrates that industrial automation, if built for the environment, can already outperform human operators in endurance, safety, and cost.
As the EV ecosystem grows, these autonomous platforms will shape not only how we drive — but whether we need to drive at all.
