I can see where Orion could work if the time allowances were accurate. Trouble is, the time allowances on most routes are not even remotely accurate! If you complain enough then they do a "virtual time study" using Google Maps or equivalent. From these maps, they can supposedly tell how many steps it is from the truck to the front door. However, I'm pretty sure they just draw a straight line through the customer's yard which I have been taught is not a safe path. And they don't give any time allowance for climbing the stairs to the 3rd or 4th floor of an apartment building. And, from what I've gathered from experience, Orion doesn't figure in traffic or stop lights at all. Every day it expects me to have made about 10 more stops before I get to my last air stop, so by 10:30am (according to Orion) I'm already about 30 minutes behind.
