What action contributes to Eco-Driving?

Selecting a high gear as soon as possible contributes to Eco-Driving because it allows the vehicle to operate at lower engine RPMs (revolutions per minute). This reduces fuel consumption and emissions, as the engine runs more efficiently at lower speeds when in a higher gear. Eco-Driving focuses on maximizing fuel efficiency and minimizing environmental impact, which is achieved by maintaining a steady speed, anticipating traffic conditions, and shifting gears at the appropriate times.

Driving at high speeds generally leads to increased fuel consumption and greater emissions, while keeping windows open can negatively affect aerodynamics, which may lead to higher fuel usage. Regularly revving the engine serves no purpose for efficient driving and can waste fuel, thus contradicting the principles of Eco-Driving.
