Deformation professionelle probably but what this makes me think of is how easy it is for a vehicle to enter Accidental Full Self Driving mode, without having any specialised equipment. For cars, just put a brick on the gas pedal and point the car in the right direction, and in some situations the car will "drive itself" for a while; even a long while. For planes or boats it's probably easier to find circumstances where this can go on until they run out of fuel.<p>Once, in another life time, I owned an ancient Horex Regina II 400 cc., a 1953 model and it came with Full Self Driving. To activate it, I simply had to take my hands off the wheel and rest them on the tank. It would keep going straight on its own, without intervention. If the road turned, all I had to do was turn my hips a bit and it would follow along.
