Can the throttle be fully depressed in first gear of a manual transmission?

Manual transmission first gear should not have the throttle fully depressed. When starting, gently press the accelerator to add a little fuel. Gear shifting precautions: First, turn on the power (without starting the engine), press the brake, shift gears—not directly into D gear, but shift to N gear first, then ignite, and then shift from N gear to D gear, release the handbrake, lift the foot brake, and start. Manual transmission usage tips: For manual shifting mode, simply switch the gear to M gear. This mode allows the driver to manually select the appropriate gear between 1st and 4th gears, enabling the car to drive as if equipped with a manual transmission, without the need to press the clutch pedal when shifting gears like in a manual transmission.
When I first started driving, I was also curious about this. Can you really floor the throttle in first gear with a manual transmission? First, the car's response will be very aggressive—the tachometer will shoot straight into the redline, and the whole car will roar. The engine can't handle this kind of abuse, especially older cars; the sudden high temperatures can easily cause cylinder scoring. I once saw a newbie do this and burn out all the spark plugs, leaving the mechanic stomping in frustration. Plus, first gear already has a high gear ratio, so it’s just a waste of fuel—driving like this in the city for two kilometers could burn an extra half-liter of gas. It’s better to gently press the throttle, shift to second gear at around 2,000 RPM, and keep both the car and yourself comfortable and safe.
