If that's the case then Fedex is still 8 years behind us & the leading edge. We had a system called RDD in our city trucks, from Qualcomm. BTW, we moved on to something newer......
This unit contained all pick up and delivery information, GPS tracking and the ability for dispatch and driver to contact each other. The office also had software to print out your whole day's travels onto a map.
I was once asked why I was off route. I asked where was I? Show me the printout. According to the printout, I should have drowned in the truck in the middle of the Hudson River. They never bothered to use that feature again, as far as they were concerned with me.
