I think one of the most fuel efficient ways to drive is to do so in a way that minimizes use of the brakes.

If you can drive on the highway without needing to brake and slow down for other traffic, then all your fuel goes toward moving your vehicle. It is not getting wasted speeding it up, for the brakes to slow it down. It means when in an area with lights not driving racing from red lgiht to red light. It means when you know a stop sign is ahead, getting off the gas and allowing the car to slow down without using the brakes before you get to the stop sign. Sure, you will have to use the brakes at times, but driving with the idea that you are trying to minimize their use is good conservative driving.
