A vehicle has a safe and a utility device operable for performing a task having a result capable of being measured. A local processor is associated with local storage, each of which is housed in a safe preventing access thereto. An operator input console associated with the local storage is carried by the vehicle and is disposed outside the safe. A positioning system associated with the local processor generates position information of the vehicle during operation of the utility device. A sensor associated with the utility device and the local processor generates result information of the result of the operation of the utility device. The local processor stores in the local storage the position information, the result information, and the operator input information. The operator input console and the local processor are adapted and arranged preventing access to the local storage in response to operation of the operator input console.
