@ Schroeder,
My tractor was equipped with a Qualcom satellite system that monitored everything. All the information regarding fuel economy, mileage, average speed etc, etc could be looked at instantly by the driver and the dispatcher. The dispatcher contacted the driver through this system too to assign loads or send messages regarding needed maintenance scheduling and any other info deemed necessary to get the load from A to B in a timely manner. It even enumerated the route to take. Any deviation would have a dispatcher pinging you to ask why you're not where you should be.
That's why I never paid it much attention because I didn't need to track it. My job was to motivate it only.
