I don't want to be insensitive, but given the recent tragedy in Glasgow, the last thing I would want is hundreds of drones zipping about our skies just waiting to drop down on top of us when something goes wrong.
I would rather see drone electric delivery vehicles on the roads.
In fact, I would prefer all vehicles on the roads to be computer-controlled, as long as the SatNav problem could be sorted out so they didn't insist on the vehicles driving up footpaths or into lanes too narrow for them.
