The car doesn't roll in first gear because first gear provides the highest amount of torque and power to the wheels, making it ideal for starting from a complete stop. The gear ratio in first gear is designed to provide maximum acceleration and pulling power, which prevents the car from rolling backwards on an incline or losing control when starting from a stop. Additionally, the engine braking effect in first gear helps to keep the car stationary when idling or at a stop. **

When a car is in first gear and the clutch is engaged, the engine is connected to the transmission, which in turn is connected to the wheels. If the car is on a slope and the clutch is released without applying the gas, the force of gravity will cause the car to roll backwards. This happens because the engine's power is not enough to overcome the force of gravity on the slope, and the car begins to roll backwards. To prevent this, the driver must either apply the gas while releasing the clutch or engage the handbrake to keep the car from rolling backwards. **

To let a car roll in gear, you simply release the clutch pedal slowly while applying a small amount of gas. This will engage the transmission and allow the car to move forward or backward depending on the gear selected. It's important to be cautious and aware of your surroundings when letting a car roll in gear, especially on an incline or in a crowded area. Always make sure to use the handbrake if necessary to prevent the car from rolling uncontrollably. **
