It wouldn't have to be while the vehicle was in motion on public roads. Think mobile warehouse: Pull into a parking area, launch the drones, collect the drones, reload. I dunno how many dozens of packages you could deliver within a mile radius or so, but it would be a lot more than the driver could drop off on his own, which is the point. And maybe someday you don't even need a driver. If this idea is going to work at all (and that's a big if) these things were always going to have to fly over roads and land in driveways.
