Does accidentally starting the car in gear have any impact on the vehicle?

If the clutch is fully depressed, starting the car in gear will not cause any damage. However, if the clutch is not depressed or is partially engaged, directly starting the engine can potentially damage the engine and brake components, and may also cause the vehicle to lurch forward, increasing the risk of an accident. When starting on a steep slope, engaging first gear can prevent the vehicle from rolling backward, but it is still necessary to depress the clutch while starting. Below is additional information: 1. Ignition: The ignition switch of a motor vehicle controls the primary circuit of the ignition coil and can be freely turned on or off. Ignition methods include mechanical key ignition, remote start ignition, and push-button start ignition. Different vehicle models may have varying ignition methods, and the appropriate ignition switch should be used based on the specific vehicle. 2. Clutch Depressing: Starting the car in neutral without depressing the clutch means the clutch remains engaged with the transmission. Although the engine's power is transmitted to the transmission, since the car is in neutral, no power is delivered to the wheels, so starting in neutral without depressing the clutch is safe. However, if starting in gear without depressing the clutch, the engine's power remains connected to the transmission, causing the vehicle to lurch forward dangerously. Therefore, when driving a manual transmission car, it is essential to develop the habit of ensuring the gear is in neutral (by shaking the gear lever side to side) and always depressing the clutch before starting the engine.
