I'm happy to say that i never worked under orion, and never will. But from what I've heard its been an absolute disaster. I was a driver who came up during the EDD years. So i can understand that the "old timers" worked by a totally different system. I do feel that EDD was a big part of learning the basics of an area. It took me a year before i felt comfortable with doing all of the different variables that came during the day. It really took my taking of a rural route where i developed the use of using maps and trying to figure out where to drop in on stops. On my final route, you could take one road and have to drive 5 miles to deliver 1 stop, then turn around and have to drive those 5 miles back to where you started. But if you postponed that stop till later in the day, you could get it from the other end of the road when you were only 1 mile away on the road that intersects it.
I do feel that the new drivers will rely too much on the technology to try and get the job done. Common sense won't come into it.
