Where can you stow your baggage so that you do not increase your fuel consumption unnecessarily?

You answered correctly by choosing the boot and behind the front seats. Placing luggage inside the car—either in the boot or behind the front seats—does not significantly affect the car's aerodynamics. In contrast, transporting items on the roof-rack increases air resistance, leading to higher fuel consumption. To save fuel, it's best to store baggage inside the vehicle instead of outside on the roof. This is an important rule for efficient and economical driving.
