The Best of Both Worlds and Other Ambiguous Tales. Brian Stableford
the Aurora. Many of the other vehicles slowed down too, so the traffic in the lanes immediately to his left wasn’t going much faster, but the vast majority of drivers had put their vehicles on automatic pilot so that they could watch the aurora, and the automata were careful to maximize the traffic flow, thus keeping speeds up to sensible levels in the outer lanes. The bridge was very busy, but not so busy that there was any threat of a traffic jam.
Tom had eyes enough to watch the aurora as well as the road, and attention enough to divide between the two with some to spare, but he seemed to be one of very few vehicles on the bridge that did—there were no other giants he could see, ahead of him, behind him or traveling in the other direction. Even if the other drivers who were on the bridge had noticed what he noticed, therefore, they would not have been sufficiently familiar with the living bridge to realize how profoundly odd it was.
It was not the mere fact that the bridge as moving that was odd—it was, after all, a living bridge, and the sea was becoming increasingly choppy—but the way it was moving. Although a shorter vehicle might not have noticed anything out of the ordinary, Tom had no difficulty discerning what seemed to be slow long-amplitude waves of a sort he had never perceived there before. There was nothing violent or febrile about them at first, though, so he was not at all anxious as he rooted idly through his archive in search of a possible explanation.
The archive could not give him one, because it could not piece together the links in an unprecedented chain of causality—but it brought certain data to the surface of Tom’s consciousness that allowed him to put two and two and two and two together to make eight when the vibration began to grow more violent, at a rapidly-accelerating pace. By the time he saw the rip opening up in the centre of the bridge’s desperate flesh, he had a pretty good idea what must be happening—but he hadn’t the faintest idea what to do about it, or whether there was anything at all that he could do. He reported it, but there was nothing the traffic police or Company HQ could do about it either; neither of them had time even to advise him to slow down and be careful.
What Tom had reasoned out, rightly or wrongly, followed from the fact that, in addition to their other effects, the showers of charged particles associated with solar storms caused flickers in the Earth’s magnetic field. Such flickers could, if the subterranean circumstances happened to be propitious, intensify and accelerate long-range magma flows in the mantle. Intensified long-range magma flows in the mantle could, if conditions in the crust were propitious, cause long-distance earth-tremors. Because it was a living structure, the Behring Bridge was able to react to minor earth-tremors in such a way as no negate their effects on its traffic, and was bound to do so by its programming. Long-distance tremors were not problematic in themselves. Unfortunately, long-distance tremors caused by long-range magma flows could build up energy at crisis-points, which could result in sudden and profound tremors that were, in seismological terms, the next worst things to detonations.
If any such crisis-point happened to be located directly beneath one of the bridge’s holdfasts, it was theoretically possible for the bridge’s own reflexive adjustments to cause an abrupt breach in its fabric. The living structure was, of course, programmed to react to any breach in its fabric with considerable alacrity—but adding one more “if” to a chain that was already awkwardly long suggested to Tom that sealing the breach and protecting the traffic might not be at all easy while the energy of the tremor at the crisis-point was spiking.
It would be highly misleading to suggest that Tom “knew” all this before the instant when the Behring Bridge began to tear, even though all the disparate elements were present in his versatile consciousness. It would be even more misleading to report that he “knew” how he ought to react. Nevertheless, he did have to react when the situation exploded, and react he did.
According to the Highway Code, what Tom should have done was to brake, in such a fashion as to give himself the maximum chance of slowing to a halt before he reached the breach in the bridge caused by the diagonal tear in its fabric. That would give the active parapet of the living bridge the best possible chance to throw a few anchors over him and hold him safely while the rent was repaired—if the rent turned out to be swiftly repairable.
Instead, Tom swerved violently to his left, cutting across the six outer lines of westbound traffic and snaking through the central barrier to plant his engine across the outer lanes of the eastbound carriageway.
The immediate effect of Tom’s maneuver was to cause a dozen cars to crash into him, some of them at high velocity—thus racking up more serious accidents within two or three seconds than a statistical average would have allocated to him for a century-long career.
One of the slightly longer-delayed effects of the swerve was to activate the emergency responses of more than a thousand other vehicles, whether they were already on automatic pilot or not—thus generating the biggest traffic jam ever seen within a thousand miles to either side of the accident-site.
Another such effect was to cause Tom’s own body to zigzag crazily, so that he had virtually no control of where its various segments were going to end up, save for the near-certainty that his abdominal mid-section was going to lie directly across the diagonal path of the widening tear in the bridge.
That was, indeed, what happened. As it followed its own zigzag course through the fabric of the madly-quivering living bridge, the crack went directly underneath the gap between Tom’s second and third containers.
As the rip spread, tentacular threads sprang forth in great profusion, wrapping themselves around one another, and around Tom. So many of Tom’s ocelli had been smashed or obscured by then that his sight was severely impaired, but he would not have been able to take much account of what he could see in any case, because he felt that he was being torn in two.
His hind end—which constituted by far the greater part of his length—was seized very firmly by the bridge’s emergency excrescences and held very tightly, blocking all seven lanes of the westbound carriageway. His front end was seized with equal avidity, but could not be held quite as securely. As the bridge struggled mightily to hold itself together and prevent the rip becoming a break, Tom was caught at the epicenter of the feverish struggle, wrenched this way and that and back again by the desperate threads. His engine swung to the right, drawn closer and closer to the widening crack, while the strain on the joint between his second and third containers became mentally and physically unbearable.
Tom had no way of knowing how closely akin his own pain-sensations might resemble those programmed into humans by natural selection, but they quickly reached an intensity that had the same effect on him that explosive pain would have had on a human being. He blacked out.
By the time Tom’s engine fell into the Arctic Ocean, he was completely unconscious of what was happening.
When Tom eventually recovered consciousness he was aware that he was very cold, but the priorities of his programmers had ensured that he did not experience cold as painful in the same way that he experienced mechanical distortion and breakage. The cold did not bother him particularly. Nor did the darkness, in itself. The fact that he was under water, on the other hand, and subject to considerable pressure from the weight of the Arctic Ocean, made him feel extremely uncomfortable, psychologically as well as physically.
Even if there had not been a solar storm in progress it would have been impossible to establish radio communication through so much seawater, but after a very long interval a pocket submarine brought a connecting wire that its robot crabs were able to link up to his systems.
“Tom?” said a familiar voice. “Can you hear me, Tom Haste?”
“Yes, Audrey,” Tom said, who had long since recovered the calm of mind appropriate to a giant RT. “I can hear you. I’m truly sorry. I must have panicked. I let the Company down. How many people did I kill?”
“Seven people died, Tom, and more than a hundred were injured.”
The total was less than he had feared, but it still qualified as the worst traffic accident in the Company’s proud history. “I’m truly sorry,” he said, again.
“On the other hand,” the robopsychologist reported, dutifully, “if you hadn’t done what you did, our
