The car has long been constructed on a tried-and-true model: four wheels and a powertrain and a steering wheel that allows the driver the most control. That steering wheel has always been the direct link between man and his vehicle and enabled the driver to respond to changing road conditions immediately. Today, however, car definitions are in flux, with autonomous driving technology still evolving. One of the biggest debates in contemporary auto law is whether or not fully driverless cars need to be fitted with manual driving controls, a question now posed by federal regulators.

The National Highway Traffic Safety Administration (NHTSA) is considering rules it has drafted for cars meant for human driving. As AI grows ever more adept at a driver’s role, regulators ask if age-old safety provisions still apply to vehicles that are never designed to be driven by a human. This discussion is not for the car, but for purpose-built autonomous vehicles, which is part of the attempt to modernise safety norms and continue on the path of technological development.

Steering wheel removal has been welcomed by autonomous vehicle developers but has also sparked a discussion about public confidence, safety, emergency response and regulation. But while most in the industry and engineering and safety communities recognize that the technology is very promising, many feel it needs to be backed by clear, open testing, performance data and emergency protocols. Rather than whether autonomous vehicles will enter the mainstream of transportation, it’s a matter of when.

1. NHTSA Considers a New Direction for Autonomous Vehicles 

In a recent statement, the administrator of the National Highway Traffic Safety Administration (NHTSA), Jonathan Morrison, said the agency is prepared to discuss removing the steering wheel from cars geared toward driverless driving. His remarks are a major change in regulatory thinking, and future federal safety regulations may more accurately reflect the capabilities of fully automated transportation systems, rather than just the requirements of vehicle design that were developed decades ago.

Rethinking Traditional Vehicle Design Standards:

• The steering wheel requirement is being reviewed.
• AI-focused vehicle regulations.
• Making federal safety requirements modern.
• Future-ready autonomous policies.
• Human-free driving concept.

Morrison said demanding human-operated controls on machines that aren’t meant for human use might not make any sense anymore. If AI takes over all driving duties, the requirement for steering wheels and pedals may become more of a hindrance than a safety measure.As AI handles all driving tasks, the need for steering wheels and pedals could be a liability, not a necessity, in the future. His comments come in the context of a general rulemaking to revise Federal Motor Vehicle Safety Standards (FMVSS) to accommodate today’s more automated transportation environment.

Morrison’s comments do not necessarily indicate that the rules will be modified immediately, but they do give the potential for a formal review of the rules for modernising vehicle requirements. Future changes would also need to be fully reviewed, open for public comment and technically assessed before it could be formalised as policy.

2. Manual Controls May No Longer Fit Purpose-Built Robotaxis 

The debate over steering wheels comes on the heels of another proposal NHTSA had come up with to eliminate the need for brake pedals in all vehicles that can be operated autonomously. These changes, Morrison said, were common sense changes to eliminate rules that are no longer relevant to today’s design of vehicles.

Eliminating Unnecessary Driver Controls:

• The Brake Pedal Rules are examined.
• Robotaxi-focused design changes.
• Smarter regulatory approach.
• Autonomous-first engineering standards.
• Manual control-free safety.

The logic behind his reasoning is based on “rules (or laws) for safety; not for maintaining a ‘traditional’ engineering assumption. The traditional controls that are not utilized during the entire life cycle of the vehicle may not be suitable for an autonomous vehicle that never decides to intervene.

The proposed changes aim at fostering innovation while continuing to maintain the level of safety expectations. Where some parts of a physical vehicle are rendered redundant, regulators continue to stress that performance, reliability and passenger protection should always be at the forefront of the driver’s mind.

3. The Proposal Applies Only to Fully Autonomous Vehicles 

The fact that the proposal is limited is an important difference. The regulation changes would only affect cars specifically designed for autonomous driving. Even cars fitted with driver-assistance systems would still have to fulfil the existing standards for steering wheels, brake pedals and other hand controls.

Limited Scope for Driverless Vehicles:

• Only adopt fully independent models.
• Conventional cars unaffected.
• Separate vehicle classifications.
• Current safety regulations are still in place.
• Robotaxi-specific regulations.

Purpose-built robotaxis and autonomous delivery vehicles are quite different from privately owned passenger cars. These vehicles are intended to have no human driving controls and regulators are considering establishing different rules for their vehicle design. This distinction will promote innovation while still providing a familiar level of safety for ordinary drivers. Consumers who buy traditional cars would not see any changes to current driving controls.

4. Autonomous Vehicle Developers may Benefit

Several companies have long been proposing regulations that would be more conducive to transport systems with vehicles that are not controlled by humans. Some manufacturers have already created a robotaxi that is equipped with no steering wheel or pedals, expecting regulatory changes.

Supporting Autonomous Vehicle Innovation:

• Easier product development.
• Reduced regulatory barriers.
• Purpose-built vehicle approvals.
• Faster commercial deployment.
• Greater manufacturing flexibility.

In anticipation of federal rules that will classify purpose-built autonomous vehicles as a vehicle class of their own, these manufacturers have kept funding production. In the event that new rules are adopted, companies would no longer have to count on temporary exemptions in order to test or deploy vehicles designed for autonomous driving. Eliminating unneeded regulatory obstacles would make development easier, deployment faster and more predictable for manufacturers putting significant resources into autonomous mobility technologies.

5. Companies are Pursuing Various Development Strategies

Not all AV companies have taken the same road to get to the point they’re at today. Some manufacturers have created a whole new vehicle that includes no steering wheel or pedals; others have decided to adapt a standard passenger car with pedals and steering wheels.

Diverse Approaches to Autonomous Development:

• Purpose-built autonomous vehicles.
• Adapted current vehicle bodies.
• Different innovation strategies.
• Gradual automation transition.
• Flexible product planning.

Several firms have been able to launch driverless ride-hail services without violating existing federal vehicle safety laws by operating on conventional vehicle platforms. This approach has simplified the regulatory landscape, but it’s also a more incremental shift towards full automation. The proposed changes to regulation could impact the development plans of the entire industry. If federal standards change, companies which now use modified passenger cars may want to consider purpose-built autonomous platforms in the future.

6. The Academy for Science and Engineering Publishes a Daily Blog

Although the autonomous vehicle industry has been growing in popularity, safety experts still stress that taking away steering wheels is more complicated than just redesigning the inside of the car. Most people think that manual control is a safe one when things go awry.

Balancing Innovation with Safety:

• Effective emergency back-up systems in place.
• Passenger protection priorities.
• Manual override alternatives.
• Public safety considerations.
• Real-world operational readiness.

If steering wheels and brake pedals are removed, then there must be equally safe options for passengers, emergency responders, and maintenance staff, industry experts say. These features, including an emergency stop system, passenger controls and standardized override processes, may play a growing role as the autonomous vehicle gains traction in the transport sector. These concerns are not antimonopolistic. Rather, they underscore the need to replace the traditional safety mechanisms with one that offers equal or better protection in real operating conditions.

7. Emergency Response Remains a Critical Challenge 

Autonomous vehicles still face new challenges in an emergency situation. In the event of an accident, construction or disaster response, it is sometimes necessary for the first responders to move, stop or reposition vehicles. Emergency responders would otherwise have to use other means of communication that can safely guide autonomous vehicles.

Preparing for Emergency Situations:

• Emergency vehicle communication.
• Passenger safety procedures.
• Fully functioning emergency stop mechanisms.
• Disaster response coordination.
• Standardized rescue protocols.

The safety of passengers is also an important factor. Road users need some easy and reliable way of stopping the vehicle or to get out safely when things get unexpected. Such “emergency” procedures should work uniformly in all operating systems and with all software upgrades. Creating standardized emergency response systems can be as critical as enhancing autonomous driving capabilities. Regulators and manufacturers continue to seek solutions to meet both the operational and public safety expectations.

8. Current Investigations Continue Shaping Policy 

NHTSA is already looking into autonomous vehicles that have had trouble navigating around construction and emergency response scenes. While these incidents are relatively rare, they are informative of areas where additional improvements can be made.

Learning from Real-World Incidents:

• Construction zone performance.
• Emergency scene recognition.
• Continuous safety investigations.
• Improving autonomous reliability.
• Real-world system evaluation.

Jonathan Morrison has admitted that even if a system fails in one instance it should be taken seriously as autonomous systems have to consistently exhibit predictable behavior in all driving circumstances. The agency has been urging AV makers to enhance their systems’ ability to identify emergency vehicles, nonstandard traffic flow and other conditions on the roadway. These continuing investigations are examples of the evolution of both regulatory modernization and safety oversight. It is important to note that fostering innovation doesn’t mean we can never check and hold someone to account again.

9. Federal Regulations Continue Evolving 

Automakers have been asking for revisions to the regulations, which were devised for cars, for years. Past exemptions were granted on a limited basis, and frequently included time-consuming review and limits on production quantities. Automakers have spent years requesting updates to regulations originally created for conventional vehicles. Previous exemption requests allowed limited deployment of autonomous vehicles but often involved lengthy review processes and restrictions on production numbers.

Modernizing Federal Safety Standards:

• Reviewing outdated regulations.
• Autonomous vehicle exemptions.
• Updating safety requirements.
• Technology-driven policy changes.
• Future mobility regulations.

NHTSA is currently considering a number of Federal Motor Vehicle Safety Standards separately to evaluate if any of these requirements are still required for vehicles developed for autonomous driving. Many other parts and components have been considered in earlier proposals, but may not be relevant to fully autonomous vehicle designs, like windshield wipers, defogging equipment, tire information labels, brake pedals, etc. This is part of a larger review of the regulations, which includes a discussion on steering wheels. Instead of updating all the rules at once, the regulators are reviewing individual rules based on their applicability to the future of autonomous transportation.

10. Balancing Innovation with Public Trust 

This is one of the major challenges in the world of autonomous transportation proving measurable safety performance. Industry experts keep saying regulators should use independent testing results and not company presentations to determine when autonomous systems are ready for the masses.

Building Confidence in Autonomous Technology:

• Independent safety verification.
• Public trust development.
• Transparent regulatory process.
• Responsible technology adoption.
• Safe autonomous future.

Morrison’s remarks are a preliminary discussion of regulation, not a policy. Federal safety standards are subject to public comment, technical review and further analysis before any permanent changes are made in the rule. The promise of an autonomous vehicle is tremendous in its ability to cut down on distracted driving, fatigued driving, and impaired driving-related crashes and increase transportation options for older adults and people with disabilities. Despite these potential advantages, removing the steering wheel is more than just a design choice. It marks a major transformation in the trust of intelligent machines in society. The prospect of this new era of automotive innovation presents a number of challenges for Washington, the most important of which will be to ensure that as technology evolves, safety, transparency, and public trust do, too.
