What are the hazards of alternately pressing the brake and accelerator pedals?

The following are the hazards of alternately pressing the brake and accelerator pedals: Abnormal noises: If the vehicle is rear-wheel drive, it may cause tire spinning on the spot; the engine may emit intense roaring sounds; manual transmission cars in high gears may stall directly, while braking in low gears may fail to stop the vehicle. Damage to the vehicle: It harms the clutch and transmission components; it may cause premature failure of the gearbox; it can burn out the clutch plates, leading to varying degrees of unnecessary repairs. Braking, also known as deceleration, refers to the action of stopping or slowing down a moving locomotive, vehicle, or other transportation machinery. The accelerator, also called the throttle, is the control device that regulates the engine's power output. It controls the throttle opening of the carburetor to manage the cylinder's filling volume, determining the engine's output power. Harm to people: If the brake is suddenly pressed hard, the occupants inside the vehicle will lean forward due to inertia, which can cause impact injuries to the passengers. When pressing the accelerator, it should be done evenly and slowly to accelerate. If the accelerator is pressed suddenly, causing the car to accelerate abruptly, it can create unsafe conditions for pedestrians on the road or the driver inside the vehicle, increasing the risk of traffic accidents.
After driving for so many years, what I fear the most is new drivers operating both pedals simultaneously. This not only doubles the load on the braking system—especially disc brakes, which can overheat and lead to brake failure—but also poses significant safety risks. In emergencies, insufficient deceleration can easily cause accidents. Over time, brake pads and brake fluid wear out faster, increasing the frequency of repairs. I've serviced many cars with severe wear due to this habit, requiring costly part replacements. Fuel is also wasted as the engine works against the brakes, burning gasoline needlessly. Developing the habit of moving your foot only when necessary can save both trouble and money.
I remember doing this when I was learning to drive—putting my foot on the wrong pedal during traffic jams. The harm is significant: forced engine braking can damage transmission components, automatic transmissions are prone to overheating, and clutch wear accelerates. From a safety perspective, the biggest concern is reduced braking effectiveness, which could double the risk on slippery roads. Fuel consumption inexplicably rises—burning gas without moving forward. Now realizing the severity, I remind myself to keep the pedals separate every time I drive, protecting both the vehicle and safety.
As an experienced driver, I've seen too many people drive like this. The main hazards lie in the braking system: overheated and warped discs, rising oil temperature leading to failure. Simultaneous throttle operation strains the engine and reduces component lifespan. It creates significant accident risks by extending braking distance. I recommend developing the habit of pressing only one pedal at a time - simpler operation.
