I believe, although in the military it may be referred to "Driver", I believe the term "Captain" is product specific and describes to the customer what level of detail the product has.
I don't know if someone purchasing the product would understand the distinction of "Driver" and may think it is a different level of product similar to an "entrance level".
Although it's not exclusive, a "Captain" (rank) could be the pilot of this aircraft. So it's not out of place, but may serve describing the product better.
