Actually it sounds like what the Prius has (one of the few good things about the prius) where is "judges" your driving based on acceleration speed etc.. to help you attain the most fuel efficient Delta Curve and speed. Keep the light green and your getting maximum efficiency.
Example braking too hard is a nono since it wastes the potential energy you spent fuel attaining and could now be converting into kinetic energy (coasting) etc..
As long as you can turn it on and off this is a GREAT idea for a GPS since the nature of what it does GIVES you a lot of the needed information anyway ie acceleration and speed.
Its amazing how much mpg you can gain with throttle control and intelligent driving (no need to go crazy hypermiling just small changes in your accelerator habits can have a big impact on your MPG)
Example when you see a light coming up "let off the gas" and let the car start slowing down. Your now using less fuel and it might change again before you even get to it negating the wasteful need to stop all together. Not enough to annoy other drivers JUST enough to smooth out the fuel curve a little.
Know when the downhill is coming up and "let off" the gas a wee early and let the hill give you a gravity boost etc.. Speed up slowly before reaching an uphill and convert some of that potential energy into kinetic energy to help you climb and crest the hill more efficiently. (accelerating slowly on level ground will take less fuel than accelerating UP the hill harder)
EVENTUALLY you will do these things (just slight does not have to be perfect or even noticeable to other drivers or you) and it will just be second nature eventually. You will suddenly realize you filling up a wee less often and spend a little less green on oil :-)
Just TINY changes in your driving habits that after a few weeks you will not even notice any longer can result in HUNDREDS of dollars in savings over the period of a year especially if your a heavy driver (lots of miles)
“An engineer explained to us that hundreds of ear impressions were gathered in the name of research, and while each one obviously boasted its own unique shape and size, one single characteristic remained uniform across the board: the entrance into the ear canal is not a perfect circle, it's an oval.”

Thats cool.
