Why Do Driverless Cars Still Have Steering Wheels?

Preview

Driverless cars, also known as autonomous vehicles, often still include steering wheels for several reasons:

Legal and Regulatory Requirements: In many regions, current regulations require autonomous vehicles to have manual controls, including steering wheels and pedals. This is to ensure that human drivers can take over control in case of system failures or emergencies. For example, the National Highway Traffic Safety Administration (NHTSA) has only recently started to allow the production and deployment of cars without steering wheels and pedals.
Safety and Redundancy: Steering wheels provide a backup control mechanism. If the autonomous system encounters an issue it cannot handle, a human driver can take over to ensure safety. This redundancy is crucial for the safe operation of the vehicle in unpredictable or complex situations.

Driver Comfort and Confidence: Some drivers may feel more comfortable and confident knowing that they can take control of the vehicle if needed. This psychological factor can be significant in the early stages of autonomous vehicle adoption.
Transitional Phase: Autonomous technology is still evolving, and many vehicles are in a transitional phase between fully autonomous and manual driving. During this phase, having a steering wheel allows for a more gradual shift towards full autonomy, giving drivers and regulators time to adapt to the new technology.
Human Oversight: Some autonomous systems require human oversight, where the driver needs to monitor the system and be ready to intervene. In such cases, having a steering wheel is essential for the driver to maintain this level of engagement.
Emergency Situations: In emergencies, such as system failures or unexpected road conditions, a steering wheel allows a human driver to navigate the vehicle safely. This can be critical in preventing accidents and ensuring passenger safety.

In summary, while the ultimate goal for many autonomous vehicle developers is to remove the need for steering wheels and manual controls, these components are currently necessary due to legal requirements, safety considerations, and the transitional nature of the technology.
