Which of the following is considered a best route for good fuel efficiency?

Choosing a bypass around a town and avoiding rush hours is important because it allows the driver to maintain a consistent speed without frequent stops and delays, which can improve fuel efficiency. Likewise, a flat four-lane paved highway provides a smooth driving surface and the opportunity for higher speeds without significant uphill climbs, which is beneficial for fuel consumption. While a route with scenic views may offer a pleasant experience, it may not necessarily be designed for optimal fuel efficiency due to potential stops or lesser-quality roads.

The option that suggests all answers are correct emphasizes that each of these routes, in their context, contributes to better fuel efficiency in different ways. Therefore, the reasoning supports the conclusion that selecting appropriate routes—whether for avoiding traffic or for the quality of the road—demonstrates an understanding of driving strategies that ultimately enhance fuel efficiency during long hauls.
