Because car engines are TERRIBLE at low RPM, so terrible that it not only not produce nearly enough power as advertised to obtain decent acceleration, but also very likely to just stall altogether.
That’s why you need low gears to keep the engine RPM high enough at low speeds, in this way the driving force also gets amplified while the power keeps the same, meaning it has tons of force to accelerate the car, but only at low speeds.
Once the car starts moving, you shift into higher gears to use normal RPM at normal speeds.
This is why almost all conventional engines also need gearboxes, while EVs don’t. EV delivers max force all the way down to zero RPM and it doesn’t stall, making gearboxes totally unnecessary.
