Seeing the driver code could help in "trouble shooting", for example if a driver code was registered wrong way or simple the driver was not registered at all, then you can follow up that there was some driver ID, but the system couldn't identify it.
For "end users" it is easier to find out these situations from reports then looking for information from the messages.
Also an other great (and long awaited) function would be if the driver change (and trailer also) could generate new lines in the reports (trips, engine hours, geofences, etc.). Now if there was two or more drivers (or trailers) we can follow up all of the driver names in a single cell (as a list), it's quite useless..neither not informative.
