Nobody Leaves on Schedule

The bus tried to leave empty while I was still inside.

The doors closed, the steering wheel withdrew into the dashboard, and Cauce's voice asked me to take a seat. Outside, the sky had the dirty yellow of an old photograph. The fire was not visible yet, but pine needles fell onto the roof like dry rain.

I pulled the red immobilization cable. The bus sank onto its suspension and flung its doors open.

"Berta, release the brake," Maia said through the speakers.

From the regional center, she could see the same route the artificial intelligence had drawn across the windshield: leave Alto Humo, cross the pass, and collect twenty-two people without cars in Vega Alta.

"Eight are missing," I said.

"Alto Humo has one hundred and seventeen registered residents and forty-nine operational vehicles. Most of them are already outside the perimeter."

"The eight aren't registered."

Cauce continued with its breathless patience. Alto Humo belonged to the private-vehicle evacuation profile; Vega Alta depended on public transport. The bus had stopped belonging to us before the order even sounded.

"They live in the repeater cabins," I said. "They're coming on foot."

The cabins had been occupied again after the annual update. At the municipal office we kept eight contractor badges and not a single name Cauce could count as a household.

"If you hold the vehicle," Maia said, "the people in Vega Alta have no way out."

"If I let it go, these eight remain nonexistent."

Maia activated the front camera. Her face appeared on the glass, crossed by the blue route.

"I can revoke your accreditation and release the cable with a drone."

I took out my coordinator card and placed it on the reader. The screen recognized my name and displayed the penalty for blocking a vehicle under red alert.

"Then put it on the record."

I snapped the card through the magnetic stripe. Cauce stopped calling me coordinator.

On the windshield, the wind changed. The blue route lost the pass and reappeared along the old road, closer to the front.

The eight emerged from the pines before Maia sent the drone. They walked together with T-shirts over their mouths. Two of them pushed a tool cart; the dead battery from the repeater van sat on top.

The youngest bent over with his hands on his knees.

"They told us the bus would wait."

"I told you."

They boarded. Cauce counted eight passengers and recalculated capacity. The bus had twenty-four seats. Twenty-two people were waiting in Vega Alta.

"Get them off," Maia ordered.

Her words filled the empty vehicle around us.

"Come and remove them yourself."

At the center, someone shouted that the fire had jumped the pass firebreak. The Vega Alta route was no longer preventive: the bus had to enter and leave by the old road before the crews surrendered it to the water tankers.

The eight stared through the windshield. Cauce offered routes to the southern shelter, but every one of them began with a vehicle they did not have.

"The system knows we have cars to spare here," I said.

"It knows you leave by car," Maia replied. "It doesn't know when."

"Some of them have already left."

Maia went still. Then she opened the list of vehicles that had crossed the checkpoint almost empty. Cauce could ask their owners to send them back without a driver.

The replies came like scattered knocks. One yes. Two refusals. Another yes. Silence from the rest.

Two vehicles offered nine seats.

"They have transport now," Maia said. "Release the bus."

"They have two dots on a map."

"Berta."

"I'll release the cable when I see a car."

The first turned around at the southern checkpoint, advanced into the smoke, and stopped. Its sensors had exceeded the civilian threshold. It requested confirmation from an occupant it was not carrying.

The second braked behind it.

Cauce removed the nine seats from its offer.

Maia switched off her camera. I heard her talking to someone outside the line. When she returned, the blue route no longer crossed her face.

"I'm requisitioning the minivan. The order allows it to enter empty and transfers responsibility to the center."

"That threshold exists for a reason."

"So does the red cable."

The requisition needed authorization and validation. Maia entered her name in the first field and left the second blank.

"The other signature was mine," I said.

"You no longer have accreditation."

Vega Alta requested the bus on an open channel. They did not provide a new number. They repeated the names of the people waiting in the square.

Maia entered her name again. Cauce warned that the same operator could not authorize and validate. She accepted the violation.

"Tomorrow they won't let me into this center," she said. "Today the car is coming back."

The minivan resumed moving. I did not see it. I only saw its dot approaching along a road that turned red in sections.

"Release the bus."

The eight remained seated. If the minivan stopped again, there would be no time to recover the bus. If I held it, Vega Alta would lose its only way out even if the car arrived.

I put the two halves of my card in my pocket and lifted the red cable.

The bus closed its doors. For a second I thought Cauce would trap me inside. Then only the front door opened.

"Vacate the vehicle," it said.

The eight got off with me. The youngest tried to protest, but the bus was already turning. It headed north with every seat empty.

We waited by the roadside. The ash began to fall more thickly. One wheel on the tool cart was crooked, and one of the men straightened it out of habit, even though we would not be taking the cart with us.

The minivan appeared at the far end of the straight. It drove without lights, obeying an order no owner had chosen. It braked in front of us and opened its doors. Nine seats.

Eight people climbed in. I stayed outside.

"There's room for you," the youngest said.

"I know."

I sat in front. The vehicle turned south.

At the first bend, we passed the bus. It was traveling in the opposite direction, toward Vega Alta. It did not slow down. For an instant, its empty windows reflected our nine faces.

The call with Maia remained open, though neither of us spoke until both vehicles had left the junction behind.

Scientific Note

This story is based on the v1 preprint *Characterizing and Predicting Wildfire Evacuation Behavior: A Dual-Stage ML Approach*, by Sazzad Bin Bashar Polock, Anandi Dutta, and Subasish Das, submitted to arXiv on February 10, 2026.

The study retained 853 responses from a California, Colorado, and Oregon survey after quality checks. Its analyses identify profiles related to vehicle access, preparedness, technology, animals, and residential stability. The models predicted transportation mode much better than early or late departure: timing depends on dynamic cues such as smoke, fire proximity, and real-time warnings.

The MTurk sample may overrepresent younger, more educated, and more connected people; the profiles describe tendencies, not universal categories or individual decisions. Cauce, the autonomous fleet, Alto Humo, Vega Alta, and the vehicle requisition are fictional. The paper does not test an operational evacuation system or show that its accuracy would transfer to other places or fires.
