ERoad at my workplace too.  Have the driver displays which gives accurate speeds and immediate feedback on any drivers performance issues (e.g over-speeds, cornering, excessive acceleration).  I don't like being tracked anymore than the next guy but there is a bigger picture to fleet management in respect of the health and safety requirements of an employer (road as well as personal safety) as well as efficiency and cost saving.  Tracking commercial fleets IMO is a no-brainier.  I like the immediate feedback we get from the eroad system rather than being called into the boss's office a week later.
