CHAPTER 42 : VEHICLE INTERFACE
The metal sang.
Not audibly—not in any way I could have explained to someone without the Armor—but the truck's frame resonated with a frequency I could feel in my bones. Steel and iron and aluminum, each material with its own signature, its own voice in the chorus of the vehicle's construction.
My hands gripped the steering wheel. The Armor extended.
Tendrils of dark matter flowed from my palms, through the dashboard, around the steering column. They wrapped the gear shift, the pedals, the frame beneath my feet. They spread like roots into the engine bay, embracing the cylinder block, threading through the fuel system, touching every piece of metal in the vehicle's anatomy.
The truck's condition flooded my senses.
Cracked cylinder head—third from the left, a hairline fracture that would fail under sustained high RPM. Worn tires—thirty percent remaining tread, adequate for normal operation but dangerous in wet conditions. Fuel at one-quarter capacity. Oil pressure low but functional. Brake pads eroded. Steering linkage loose.
I felt every flaw like injuries in my own body. The cracked cylinder was a pulled muscle. The worn tires were calloused feet. The low oil pressure was dehydration, the eroded brakes were brittle bones, the loose steering was a joint that wouldn't quite track.
"You look like you're about to be sick," Nux said.
He stood beside the truck's open door, watching me with the careful attention of someone who had spent his whole life around machines. His eyes tracked the Armor's tendrils—visible now, spreading through the vehicle like dark veins.
"Sensory overload," I managed. My voice sounded distant. "It's a lot of information at once."
"You're inside it." Nux leaned closer, studying the connection. "Not just touching it. You're inside it."
I tried to explain what I was experiencing—the engine's rhythm like a heartbeat, the frame's structural integrity like bone density, the electrical system's flow like blood through veins—but the words came out fragmented, inadequate.
"Drive it," Nux said.
"What?"
"You're inside it. So drive it. See what that feels like."
I turned the key. The engine caught, coughed, settled into a rough idle that I felt as a persistent tremor in my chest. The cracked cylinder head vibrated wrong—I could feel the pressure loss, the inefficiency, the mechanical compromise.
I put the truck in gear.
We rolled out of the motor pool and onto the Citadel's lower access road—a carved path that wound down the rock face toward the desert floor. Nux rode passenger, his hands braced against the dashboard, his War Boy instincts alert for any sign of trouble.
The first thing I noticed was the absence of delay.
When I wanted to turn, the truck turned. Not after the normal mechanical lag of wheel-to-tire-to-road—immediately, as if my intention and the vehicle's response were the same thing. The steering linkage's looseness was still there, but I compensated for it automatically, the Armor adjusting the connection to account for the mechanical flaw.
"Faster," Nux said.
I accelerated. The engine's vibration intensified—the cracked cylinder protesting the increased demand—but I could feel the limits, the precise point where pushing harder would cause failure. I stayed just below that threshold, maximizing output while preserving function.
The road curved. I took it faster than the worn tires should have allowed, feeling the grip through the rubber like nerves in my fingertips. The truck's weight shifted—I felt it as a change in my own balance, adjusting my input to compensate before the skid could develop.
"You're not driving it," Nux said. His voice was quiet, awed. "You're wearing it."
He was right. The truck had become an extension of my body—a metal exoskeleton with wheels instead of legs, an engine instead of a heart, a fuel tank instead of a stomach. I didn't operate controls; I moved limbs. I didn't read gauges; I felt conditions.
The road straightened. I pushed the truck to its mechanical limits, feeling every component strain, every connection hold. The Armor transmitted data in real-time—temperature, pressure, stress, wear. I knew exactly how hard I could push and exactly when I needed to back off.
We completed a circuit of the lower road and returned to the motor pool. I brought the truck to a stop, killed the engine, and sat for a moment with my hands still on the wheel.
The Armor was reluctant to disconnect. The tendrils had settled into the vehicle's frame, comfortable in their extended configuration. Pulling them back felt like prying fingers loose from a handhold.
I let go.
The disconnection hit like stepping off a moving platform.
For thirty minutes, I had been a vehicle—four wheels, several tons of metal, an engine that burned fuel and converted it to motion. Now I was a person again, two legs, organic weight, a heart that pumped blood instead of gasoline.
Phantom limb syndrome. Except the missing limb was an entire truck.
I flexed my hands, feeling the ghost of a steering column that wasn't there. My feet pressed against the floor, expecting pedals that had vanished. The world seemed smaller, more limited, confined to the narrow boundaries of a human body.
"That was the strangest thing I've ever seen," Nux said. He was grinning—the expression of a War Boy who had witnessed something chrome. "Can you do that with any vehicle?"
"I don't know." My voice sounded strange to my own ears—too quiet, too contained after the engine's roar. "That was the first time."
"But you'll practice?"
"I'll practice."
Toast arrived within minutes, drawn by the motor pool's activity. She circled the truck, examining the points where the Armor's tendrils had contacted metal, searching for visible signs of the interface.
"Structural integrity unchanged," she said, running her hands along the frame. "No degradation. No residue. Whatever you did, it didn't damage the vehicle."
"I could feel everything," I said. "Every flaw, every weakness. I knew exactly what was wrong with it and exactly what it could still do."
"Diagnostic integration." Toast pulled out her notebook and began writing. "The Armor serves as a comprehensive sensor system when interfaced with a vehicle. You feel mechanical conditions the way you'd feel physical sensations in your own body."
"And the control response was immediate. No delay between intention and action."
"Neural bypass. You're not sending signals through mechanical systems—you're sending them through the Armor directly." She looked up from her notes. "This is significant. If you can interface with any vehicle, you become a combat driver that no one can match."
"Assuming I can maintain the connection under stress."
"Assuming that." She closed her notebook. "We need controlled testing. Duration limits, stress thresholds, disconnection effects. The phantom sensation you're experiencing suggests the interface has psychological components we need to understand."
Nux was already climbing into the truck's driver seat, examining the controls with renewed interest. "If he can feel a vehicle's flaws, he can tell us exactly what needs repair. No more guessing about engine problems. No more wasted parts on trial-and-error fixes."
The tactical implications were obvious. The diagnostic implications were equally valuable. And the psychological implications—the phantom wheels, the sensation of being something larger than human—were concerning enough that I needed to understand them before relying on the capability in combat.
"I'm adding this to the training rotation," Toast said. "Thirty minutes of interface practice per day, with documented effects. We need to know your limits before you push them."
I nodded. The decision was sound, even if part of me wanted to climb back into the truck immediately, to feel that expansion of self, that merging with metal that made the human body's limitations seem trivial.
That desire was concerning too.
That night, I lay in my bunk flexing my fingers and feeling the ghost of a steering column that wasn't there.
The truck was in the motor pool. I was in my quarters. But some part of me was still driving—still feeling the road through tires that weren't attached to my body, still sensing an engine's rhythm that had gone silent hours ago.
The disconnection shock was fading, but slowly. Each time I closed my eyes, I saw the view from behind the windshield. Each time my hands moved, they expected resistance that wasn't there.
Through the Network, I felt my six connections settling into sleep—the usual gradient from waking to unconscious, each mind following its own path toward rest. Nux's excited energy from witnessing the vehicle interface. Toast's analytical processing of the data she'd collected. The Dag's quiet satisfaction from another day of growth in the garden. Mors's pain-laced exhaustion as his tumors consumed another fraction of his remaining strength.
And the two newer connections—former Wretched who had volunteered after seeing the Network's benefits—drifting toward dreams I couldn't quite read.
Something flickered at the edge of my awareness.
Not one connection. Two. Both of the newer members, their dream-states synchronizing in ways that shouldn't have been possible without deliberate effort.
I reached toward them, trying to understand what I was sensing—
The sealed door.
Both of them were dreaming about the sealed door. The same door I'd discovered on my third day in the Citadel. The door that made the Armor recoil in recognition and fear. The door that Joe had visited once and come back changed.
They were dreaming about it in parallel, their unconscious minds creating nearly identical images of ancient metal and humming stone and something vast and patient and hungry waiting on the other side.
Neither of them had ever seen the sealed door. Neither of them knew it existed.
But they were dreaming about it anyway.
And somewhere deep in the Citadel's rock, I could have sworn I felt something hum in response.
