In school we learned ” what you save in energy, you have to increase the way.” By that rule you should use the exact same amount of energy (fuel) for the same distance no matter what speed. I’ve asked a few people, but no-one could give me a good answer.

The explanations that others are giving are all correct, but I’d like to add one small detail, drag and inefficiencies are the most important factors but the kinetic energy of the car is also important:
The kinetic energy scales with the square of the velocity, while the distance traveled is directly proportional to the speed, and every time you brake and accelerate again you have to give spend that energy again.
