The Stakeholder Map – Who Builds, Regulates & Operates Autonomous Mobility

Autonomous driving is not a product. It’s an orchestration. Behind every vehicle without a driver is a network of actors – developers, regulators, operators, and enablers – each with their own rules, risks, and responsibilities.

In this concluding part of our series, we look at who actually makes autonomy happen. From code to concrete, we trace the value chain of autonomous mobility – and why collaboration, not disruption, is the true driver of progress.

The OEMs and Tier 1s: Building Platforms, Not Just Vehicles

At the base of the mobility stack are the traditional vehicle manufacturers. Whether legacy giants like Volvo and Mercedes or next-gen builders like Einride and ZF, OEMs still carry the core responsibility: building platforms that can safely host autonomous stacks.

But autonomy changes the rules. Vehicles are no longer defined by horsepower and mechanical refinement, but by software readiness, system openness, and modularity. That’s why Tier 1s – suppliers of braking, steering, and electronic systems – are now partners in vehicle intelligence, not just parts.

Arnold NextG sits here as a deep-tech Tier 1 supplier, embedding Drive-by-Wire, safety, and teleoperation capabilities into vehicles before autonomy software is even activated.

The Stack Providers: Software That Sees, Thinks, and Acts

On top of the physical platform lives the software brain. Companies like Mobileye, Oxbotica, NVIDIA, and Apex.AI provide modular software stacks that interpret sensor data, plan routes, predict behavior, and control the vehicle in real time.

These stack providers must do more than code – they must certify, simulate, and prove every decision-making module under ISO 26262 and, increasingly, under UL 4600. It’s not enough to avoid mistakes – their software must fail safely, log data, and allow forensic analysis post-incident.

Most stack providers rely on robust, fail-operational control systems like NX NextMotion for certified execution of their commands—because even perfect logic is useless if the actuator doesn’t respond.

Regulators and Standards Bodies: Certifying the Invisible

Unlike past automotive revolutions, autonomy advances faster than regulation. Authorities like UNECE, ISO, and national ministries – such as Germany’s BMDV – are playing catch-up, translating innovation into legally operable frameworks.

UNECE R155 and R156 introduced cybersecurity and software update mandates. ISO 26262 governs functional safety. UL 4600 is emerging as the de facto standard for autonomy-level system certification.

But now, the regulatory landscape is gaining speed – and substance:

• Germany laid the groundwork with the Autonomous Driving Act (2021), enabling SAE Level 4 vehicles in regular traffic. As of December 2025, the Remote Driving Ordinance (StVFernLV) further authorizes teleoperated vehicles in real-world use – with explicit technical and accountability requirements.
• Switzerland followed in March 2025 with its own regulation for automated driving, including provisions for steering systems with no mechanical backup.
• China will implement Standard GB17675-2025 in July 2026, permitting full electronic steer-by-wire systems without mechanical linkage.

The takeaway: The classic mechanical steering column is no longer a regulatory requirement. Across major markets, the foundation for software-defined vehicle control is being laid – globally and fast.

This shift signals a new role for regulators—not only as compliance bodies but also as test facilitators, through sandbox programs like Germany’s PEGASUS and cooperative pilots worldwide. They're not just writing rules – they're enabling real-world deployment.

Operators and Fleet Owners: From Drivers to Supervisors

Autonomous mobility shifts the focus from selling cars to managing fleets. Public transport companies, logistics firms, defense units, and mining operators become the new vehicle owners – tasked not with driving, but with supervising, maintaining, and integrating.

Operators must invest in:

• Remote control centers
• Cybersecurity and software maintenance
• Fleet management dashboards
• Incident response and legal liability handling

This is not a minor upgrade – it’s an entirely new operational model. Many are turning to integrators and system providers to bridge that gap.

System Integrators: The Missing Link

Few actors can build autonomy alone. That’s where system integrators enter. They connect Drive-by-Wire with AD stacks, connect vehicles with cloud dashboards, and connect operators with training and infrastructure.

Arnold NextG works closely with these integrators to ensure its safety systems are not just installed – but fully embedded, certified, and ready for live operation across industries from defense to logistics to smart agriculture.

Conclusion: Autonomy Is a Team Effort

Autonomous driving is not a competition of technologies – it’s a convergence of actors. No single company owns the full stack, the rules, or the customer. Only when platform builders, software architects, regulators, and operators work in harmony can autonomy move from the lab to the landscape.

At Arnold NextG, we’re proud to be the invisible link that makes this ecosystem function. Not as the face of autonomy – but as the backbone.
