To drive in a **comfortable and safe** manner, it is important to maintain a **proper posture** in the seat. This means that the **legs should be slightly bent** and not fully extended. This position allows you to reach the pedals without straining your ankles and prevents fatigue while driving.

- **Straight body**: The back should be supported by the seat back, which facilitates access to all the vehicle's controls without the need to lean forward. This is crucial for reacting quickly to any unforeseen events on the road.

- **Avoid the submarine effect**: Tilting the seat too far back can be dangerous, as in the event of an accident, the body could slide under the seatbelt. Keeping the backrest in a more upright position helps prevent this risk.


In summary, the correct driving posture is with slightly bent legs and a straight body, ensuring comfort, safety, and better responsiveness at the wheel.
