If you buy one of these 'driverless' cars do you still sit behind a set of 'override' controls or is there just comfortable seating?
Are 'pilot-less' aircraft being remotely piloted from the ground, or are they flying 'pre-programmed'?
If they being remotely flown from the ground, is the only benefeit the redundancy of one extra crew member, or is said 'ground pilot' going to be expected to monitor/step in when required several aircraft at once?
How difficult would it be for a university educated terrorist to hack into the flight control system remotely and have himself a lovely little 9/11 encore from the secure luxury of his cave?
I just don't see the point in it all to be honest.
