I found miriam's story kind of funny. I think that taken slowly around the corner, chances are good the piano would have made it. So many people think they can drive "normally" with a high center of gravity load in the back. Yup, tie it down. Here they ticket fairly aggressively for an unsecured load. Any machine I pick up in a cabinet is put in the "back seat" of the truck, and snuggled in with the front seat so it can't move. The head is removed and put on the floor, so it can't come crashing out on one of our bad roads. (It probably wouldn't happen, but I've bought some pretty rough cabinets and those machines are heavy. Not to mention if the screws for the hinges are loose.) I've had one head tip over on the floor, but that's it.
