If the guidance failed, then as everyone knew the brakes would go on automatically, and the vehicle would stop in less than a hundred metres. Only on the outermost lanes was there any possibility that a car could go over the edge; that would require a total failure of guidance, sensors and brakes, and might happen once in twenty years.
So far, so good. But then the Chief Engineer added a caveat. Perhaps he did not intend it for publication; possibly he was half-joking. But he went on to say that, if such an accident did occur, the quicker the car went over the edge without damaging his beautiful bridge, the happier he would be.
Needless to say, the Bridge was eventually built with wire deflector-cables along the outer lanes, and as far as Rajasinghe knew no-one had yet taken a high-dive into the Mediterranean. Morgan, however, appeared suicidally determined to sacrifice himself to gravity here on Yakkagala; otherwise, it was hard to account for his actions.
Now what was he doing? He was on his knees at the side of the Elephant Throne, and was holding a small rectangular box, about the shape and size of an old-fashioned book. Rajasinghe could catch only glimpses of it, and the manner in which the engineer was using it made no sense at all. Possibly it was some kind of analysis device, though he did not see why Morgan should be interested in the composition of Yakkagala.
Was he planning to build something here? Not that it would be allowed, of course, and Rajasinghe could imagine no conceivable attractions for such a site; megalomaniac kings were fortunately now in short supply. In any event, he was quite certain, from the engineer's reactions on the previous evening, that Morgan had never heard of Yakkagala before coming to Taprobane.
