Actually, I think that long haulers are going to be the ones that first suffer. When you need a human there anyway to sign/unload/etc, then having that human also be a driver isn't such a huge problem. With long-haul the only thing that the human really needs to do is drive, and then, if needed, you could have a staging area to get the truck into the city… in much the same way that road-trains are dealt with.
