The lowering sun was getting in her eyes a bit, so she had her glasses on. Local situation reports, summarised from police radio chatter, social and mass media, and radio-station call-ins, scrolled in the bottom left-hand corner of her shaded vision. Nothing much was happening: a traffic snarl-up at Highbury Fields, a street scuffle out in Muswell Hill. In the bottom right corner a black app, patched from Hugh’s phone, traced the slow progress of the truck on which Hugh had hooked a lift. Right now, it was negotiating the one-way system at King’s Cross. With Holloway Road about ten minutes’ walk away, they were in good time to meet it.
The trolley wheels juddered and bumped on the uneven pavement, each jolt giving Hope a split-second advance warning of where to place her heel, and each lurch making her grab for one of the upper bags. It didn’t seem right that at this time in history, cracked and tilted flagstones should be a nuisance, but icy winters and rainy summers did their work regardless: freezing and erosion, two of the implacable processes that James Hutton had, with a wild surmise that had led him to search for and find the rocks that demonstrated it, held to account for the whole history of the Earth. No vestige of a beginning, no prospect of an end…
A bag slithered. Hope caught it and stopped to sling it and another two awkwardly on her shoulders, and pressed on with a surer step. She must, she thought, look a bit oppressed, trudging along like this behind the men of the house. In this instance she preferred walking behind, because it let her keep an eye on them.
Minute yellow flowers drifted down from a tree she passed under, around which a peculiar smell, like honeysuckle but with a sharper, almost aniseed note, hung like a vapour. The flowers, or perhaps floating seeds, looked like tiny cogwheels. It bothered her that she didn’t know enough to identify them as natural or synthetic. If for any reason she never returned from this flight, or holiday, or adventure, she would always regret not having done more with the back garden. She’d planted a few rose bushes and a clump of sunflowers, but most of her effort in the garden had been a holding action against its return to the Thames Basin’s local version of the climax community, slightly contaminated by stray syn bio weeds.
Her mind returned to what Hutton saw, the slow cycle of erosion and uplift, and she found herself wondering about whether it might be possible to tell if Hugh’s visions showed the past or the future, according to whether or not synthetic biology plants featured in what he saw. It needn’t even be in the landscape, in the visible biota. It could be some scrap or trace in a garment, a tool or a jewel. A whole new discipline rose in Hope’s imagination: psychochronobotany.
She laughed, and hurried on forward to where Nick and Hugh stood at the corner of Holloway Road, waiting to cross, silhouetted against the sunset sky.
The lorry came up Holloway Road, quiet on big fat tyres, a cab up front and a long container trailer behind. When it was about a hundred metres away, Hope watched its icon on her glasses brighten and begin to flash. Hugh stepped forward, waving his phone like a hitch-hiker. The truck slowed, indicated, and pulled in as close to the side of the road as it could get, the cab just beside the waiting family.
Hugh’s thumb twitched on his phone, and the side door of the cab swung open. He scrambled up the ladder, hauling his backpack, then turned around and reached out for Nick as Hope handed him up. Hope passed up her guitar and bags, folded the trolley, and climbed into the cab. Hugh was in the driver’s seat, Nick in the middle, both strapped in. She reached to slam the door, but it swung slowly shut by itself, closing with a muffled thump and a firm snick, like a bank vault.
‘Buckle up, Mum,’ said Nick, as if trying to sound grown-up. His voice piped a little. It wasn’t often he’d even been in a vehicle, other than a bus. Hope tousled his hair and fixed her lap-and-diagonal strap, settled in, and gave the thumbs-up. Hugh grinned, tapped on his phone, and sat back. The indicator light on the dash flashed, the gear changed from neutral to first, the engine rumbled, and the brakes relaxed with a loud hiss. The lorry pulled out and joined the stream of traffic, up the incline and under the bridge.
Hugh sat back, hands clasped behind his head, obviously tempted to put his feet on the dash. Nick’s gaze switched back and forth from the buildings and traffic to the movements of the gear stick and steering wheel.
‘It’s like there’s an invisible man driving,’ he said.
‘Oh, that’s good,’ said Hope. ‘It’s called the automatic driver, or drone driver, and it kind of is like an invisible man, but it’s a program in the lorry’s computer.’
‘I know that,’ said Nick, scornfully. He patted the toy monkey on his lap. ‘I was just explaining to Max. I don’t think Max understands AIs.’
‘Oh, I’m sure he does,’ said Hugh. ‘You just have to explain it to him in very simple terms.’
Which, for the next five kilometres or so, Nick did.
Hope woke from a doze. Black road, white lines, blue signs. Bioluminescent trees lined the motorway, the light they cast easily visible because the lorry’s headlights weren’t on – they didn’t need to be, except when behind a human-driven vehicle, and there were none such in the two lanes reserved for vehicles on autopilot.
‘Where are we?’ she asked, stretching her legs and wiggling her shoulders.
‘Halfway up the M1,’ said Hugh.
‘Nick should be—’
‘He is,’ said Hugh. ‘There’s a wee bunk in the back. He’s even in his PJs.’
‘Good for you. What have you been doing?’
‘Reading. Staring out the window.’
‘Are we going to pull off any time soon? I need a pee.’
‘There’s a perfectly good toilet in the back,’ Hugh pointed out.
When she returned, she took her boots off and tilted her seat back.
‘There’s a coffee machine and everything, a regular wee galley. It’s sort of mad, all the comforts for a driver who nine times out of ten won’t be there.’
Hugh rubbed his eyebrows, yawned. ‘Economies of scale. You couldn’t drive like this in Turkey.’
‘Uh-huh.’
Hope gazed out of the window again. The truck sometimes overtook other vehicles – buses, usually, with a bored driver, there only as reassurance, dozing or reading in the front seat – or was overtaken itself. Looking into the empty cabs as they drew level was a little unnerving, and those which, like theirs, contained people dozing or chatting even more so. There didn’t seem to be any pattern to the overtaking, the slowing and accelerating, but there was a rhythm. The drone-driven vehicles had no speed limit, and generally moved at over a hundred miles an hour, but she always had the feeling there was a safe distance between them – shorter than the human safe distance, because of the machines’ reaction time. At one point they passed through a heavy shower of rain, and the windscreen wipers didn’t come on until Hugh, with an irritated gesture, flicked the lever. Hope found some reassurance in the steady whump.
She dozed. After a while, a shift in the engine’s note and a sway to the side woke her up, as the lorry pulled off for a service area. It rolled, with perfect timing, into a vacant slot by a row of fuel pumps. The moment the engine stopped, she heard clangs and bumps from behind, followed by the throb of the pump and the sound of flowing liquid. The same process was being carried out on the trucks in front, the hoses and nozzles moving like hand-puppet snakes.
