The (common) law of man over (civilian) vehicles unmanned

My commentary is restricted to two issues raised in the precis article: (a) what response might the law make to autonomous or semi-autonomous unmanned ground vehicles (UGVs) on public roads; and (b) whether the use of unmanned vehicles, and especially the use of unmanned aerial vehicles (UAVs), will require the laws protecting privacy to be reviewed. A further limit on my commentary is that I can speak with any confidence only on the current law in Australia and New Zealand. I comment on the possible effect of the advent of unmanned vehicles on the law in England, Canada and the United States, but beyond those countries, I regret that my knowledge is insufficient to make any meaningful commentary.
