Why is there an empty space under the steering wheel?

There is an empty space under the steering wheel to provide driving space for the driver. Introduction to the steering wheel: The steering wheel is a wheel-shaped device used to control the direction of cars, ships, airplanes, etc. Its function is to convert the force applied by the driver to the edge of the steering wheel into torque and transmit it to the steering shaft. Functions of the steering wheel: The steering wheel is generally connected to the steering shaft via splines. Its function is to convert the force applied by the driver to the edge of the steering wheel into torque and transmit it to the steering shaft. When using a larger-diameter steering wheel, the hand force required by the driver can be reduced. The steering intermediate shaft serves as a connecting component between the steering gear and the steering shaft, which facilitates the standardization of the steering gear, compensates for errors during manufacturing and installation, and makes the installation of the steering gear and steering wheel on the vehicle more reasonable.
I've always thought it's quite normal to have an empty space under the steering wheel, mainly for safety considerations. During driving, if a collision occurs, the legs need space to cushion the impact and avoid injury. Engineers deliberately designed this area to allow drivers more freedom to move their feet, especially during emergency braking to prevent legs from getting stuck. I remember when I changed to a new car last year, the dealer mentioned this is standard design in modern vehicles. Many older cars lack this space, making the driving position feel cramped. It not only improves comfort but also reduces risks during accidents, which is emphasized by national regulations. Whether driving on highways or in traffic jams, having more legroom makes driving less tiring. Don't underestimate this detail - it could be life-saving in critical moments.
I think the empty space under the steering wheel is mainly for functional design convenience. Manufacturers usually reserve that area to install different components, such as steering column adjustment levers or control buttons, which vary depending on the vehicle configuration. Some high-end cars have buttons installed there, while my own car doesn't, but the interface is still there for potential future upgrades. Engineers designed it this way to make production lines more efficient—one mold can be used for multiple vehicle models. When I modified my car, I noticed there are also cable channels there, making it easier to operate during maintenance. Overall, this isn't laziness but a smart design that saves costs and offers users more flexibility for upgrades—a thoughtful arrangement.
