Will the car roll away if parked in P gear without engaging the handbrake?

[McGarrett]

Parking in P gear without engaging the handbrake will not cause the car to roll away. Parking precautions are as follows: 1. Basic principle of parking: When parking, consider not only your own convenience for entering and exiting but also others', and more importantly, potential unexpected situations. 2. Waiting at signals: For waiting times exceeding one minute, it is advisable to turn off the engine to save fuel and be environmentally friendly. For waits under one minute, you may keep the engine running, shift to neutral, and engage the handbrake, but never leave the car in gear. 3. Maintain distance when pausing on the road: During traffic jams or while waiting at traffic lights, always leave enough space to maneuver out in case the car ahead breaks down, preventing you from being stuck in the middle.
