Is it possible to achive high fuel efficiency by maintaining optimum speed?

Did you know that you can save fuel and run your car on water

The idea is to record a particular vehicle speed and fuel consumption over a long period by the vehicle itself. Now if the topology of the roads(ups and downs) that the vehicle frequents is known then the vehicle speed can be modulated by past experience to maximize fuel efficiency by prompting to limit speed before a down and prompting to accelerate before an upward ramp on the road.
The idea is to minimize engine braking power used so that fuel will be used for locomotion and not for limiting speed.

Modern cars don’t use fuel when the car is pushing the engine. The ECU reduces the injector pulse to zero when there is high vacuum (throttle is closed) and at more then idle rpm.
Yes, it works. I’ve owned 2 Lincolns now. They have a digital ‘instant fuel economy’ gauge and an ‘average fuel economy’ gauge.
Using those, I’ve been able to experiment with my daily driving habits and increase my fuel economy.
As a test of accuracy, I’ve checked real gas mileage the traditional way by recording mileage and gallon’s to fill back up and the gauges are always accurate within +/- .5 mpg.
Every car should have those gauges.
