What is true about accelerating?

Rough acceleration can indeed cause mechanical damage, making this statement accurate. When a vehicle accelerates abruptly, it can place excessive stress on various components such as the engine, transmission, and drivetrain. This harsh treatment can lead to premature wear and tear, potentially resulting in costly repairs or decreased longevity of the vehicle. Smooth acceleration allows the mechanical systems to work more efficiently and reduces unnecessary strain, promoting better vehicle health over time.

In contrast, the other options present misconceptions about acceleration. For instance, while accelerating can improve control when done smoothly, sudden or rough acceleration can have the opposite effect. Additionally, accelerating aggressively often leads to poorer fuel efficiency rather than enhancing it. Finally, smooth acceleration is not only beneficial but crucial for maintaining vehicle control and efficiency.
