Mileage app that uses car dock?

[monkeypimp]

does anyone know of a mileage app that starts when you put it into the car dock and records your route and mileage via GPS until you remove it from the car dock? It seems like it would be a great addition to one of the car apps out there.

I hate having to remember each and everytime I get in the car to record my mileage so i know whether its personal or business... with an app like this I can just see what the mileage is every trip and then look at where i went and i would know if its work or personal.
