"I've been on driverless trains in Paris, and Singapore (the entire MRT is automated). The TGV, Bullet and ICE are both semi-auto, with the TGV designing the driver entirely out of the operation in an emergency..." - courtesy of *Lancer*.
And in an emergency - or a complete failure of these driverless vehicles - where do they end up?
They come to a grinding Stop - on a line, on the ground, and the pax disembark on to the grass at the side.
And if the same were to happen to a pilotless aircraft, where would IT end up?
In a smouldering great hole in the ground, in a scene perhaps reminiscent of the Twin Towers on Sept 11, 2001.
And the Pax???
No prizes for guessing the right answer to that one!
