Do I need to keep pressing the brake when in N gear?

You don't need to keep pressing the brake when in N gear. N gear is neutral gear: In this gear, the transmission is also in a no-load state, but the vehicle can move. Unlike P gear, the transmission is not locked. Therefore, if you want to use the air conditioning while in N gear, you must engage the parking brake (handbrake) to prevent the vehicle from rolling. Definition of car braking: Braking, also known as stopping, refers to the action of stopping or reducing the speed of moving locomotives, vehicles, other transport tools, or machinery. The general principle of braking is to fix a wheel or disc on the high-speed shaft of the machine and install a corresponding brake shoe, band, or disc on the machine base, which generates braking torque under external force.
When shifting to Neutral (N) gear in an automatic transmission car, I recommend keeping your foot on the brake pedal for safety. Neutral gear means the car is disengaged from the drivetrain and may roll, especially on slopes or uneven surfaces. I once experienced this in a parking lot – without the brake applied, the car slightly rolled and nearly hit a nearby object. The reason is simple: N gear disconnects the power but doesn't lock the wheels, so applying the brake prevents unintended movement. In daily driving scenarios like brief stops at traffic lights, some drivers shift to N gear thinking it saves fuel, but the risk of not braking outweighs any benefit. It's actually safer to either stay in Drive (D) with the brake pressed or shift to Park (P). Ultimately, developing safe driving habits is crucial. Consistently using the brake can prevent many potential accidents, particularly in crowded urban areas.
Shifting to N gear doesn't necessarily require keeping the brake pedal pressed constantly, but safety depends on the situation. Personally, when I drive, I can briefly release the brake on flat roads or in parking lots, but I remain vigilant. After shifting an automatic transmission car to N gear, the power disengages, and the car might slide slightly, especially on slopes where you must keep the brake pressed. For example, once in a garage, I forgot to press the brake, and the car slid a short distance, nearly causing an accident. Now, whenever I shift to N gear, I instinctively press the brake for peace of mind. However, for prolonged stops, like waiting to pick up kids from school, it's better to shift to P gear and engage the handbrake or simply turn off the engine—this saves fuel and avoids distractions. Developing this small habit ensures smoother trips.
