        • Weightless Steering Wheels:
          Audi’s "Virtual Cockpit Plus" and Genesis’s "Steering Feel Control" use hydraulic dampening to reduce steering effort by 25%, mimicking the feel of a 10.5:1 ratio (vs. traditional 14:1). This lowers arm fatigue during highway cruising.
        • Pedal Modulation for Customizable Effort:
          The Porsche Taycan and Lucid Air offer adaptive throttle response, allowing drivers to adjust pedal sensitivity via an app. Mercedes’ "Active Brake Assist" integrates with pedal feel modulation to reduce leg strain during regenerative braking.
        • Driver Posture Monitoring:
          Tesla’s "Driver Attention System" and BMW’s "Active Driving Assistant" use infrared cameras to detect slouching or improper seating angles, issuing haptic seat vibrations to prompt adjustments. Studies show this reduces driver fatigue by 20% on overnight trips.
