Decades ago, CITS. It was a system to keep track of "Corporate Inventory In Transient". The idea was to track inventory in Trucks.

This may seem useful, but with what I know now, it was to track inventory for a reason that was border-line illegal. During Inventory time, trucks would be loaded up and they would cruse the Highways until the Inventory was over. They wanted a way to know what inventory was on a sightseeing trip.

That company went out of business over 30 years ago and no longer exists.
