Will the car roll away if the handbrake is engaged but not in P gear?

[MaggieRose]

P gear's automatic parking uses the gear position as a brake, so it is relatively safer and less prone to rolling. On the other hand, the handbrake uses brake pads for braking, which can easily wear out and cause the car to roll. Introduction to P gear: P gear is the most common gear in automatic transmission models, usually located at the foremost position of the gear shift console, in front of the R gear. Its purpose is to lock the axle when the car is stationary on a slope. Parking gear: When parking an automatic transmission car, it must be put into P gear along with the handbrake. For manual transmission cars, it is best to leave it in first gear and engage the handbrake, because the first gear has the highest gear ratio, making it harder to push.
