It's unsafe, because they load packages in the car that are so huge and heavy that one person cannot safely deliver them. And don't give me the message center for help crap, because this company runs with the fewest routes, and everyone else is over loaded, and cannot take time out of their day to help with an over 70. That driver assist only works in a perfect world. I haven't seen this much furniture since my last stroll through Rooms to Go. All this crap says mechanical lift only, that should give you a clue, or team lift only. They better start installing lift gates on the back of the cars, or put two people on a car or the injuries are going to go through the roof. The Post office gets all the small stuff from us, and we are left with Beds, Gas Grill, Entertainment Centers, Dressers, tread mills, and the list goes on and on.
