Which one of the following does NOT maximize fuel economy?

The choice that does not maximize fuel economy is related to the overuse of the brake pedal. Frequent and unnecessary braking can lead to a decrease in fuel efficiency because it requires the driver to accelerate again after braking, which consumes more fuel.

When a driver frequently presses the brake pedal, it interrupts the vehicle's momentum and requires the engine to work harder to regain speed, directly impacting how efficiently fuel is consumed. Maintaining a smooth driving style, which involves minimal braking and smooth acceleration, is key to maximizing fuel economy.

In contrast, maintaining good tire pressure, driving at steady speeds, and ensuring ample space margins all contribute positively to fuel efficiency. Good tire pressure reduces rolling resistance, steady speeds help avoid unnecessary acceleration and braking, and ample space margins enable better anticipation of traffic, reducing the need for abrupt stops and starts. Together, these practices support not just safety but also fuel-efficient driving.
