I currently manually search for the best fuel prices in my home area. Then for my commute to work, and then when I get to work I search that area too and then find the cheapest fuel.

What if this could be an automated process (fuel saver) for when you aren't desperate for fuel (search home area, along regularly travelled routes, and around regular destinations). My fuel cost is often around 2-4% cheaper by doing this!

It could also be tuned for savings vs effort/cost of driving out your way to get a better price.

The point of this feature, finding cheaper fuel in general for very little effort.
