AV recovery holding is a secure, observed, time-bounded place where a fleet holds a disabled, flagged, or pulled-from-service robotaxi until it can be retrieved, inspected, or cleared. It is a ground-service function, not parking.
When a robotaxi is disabled, flagged for review, or pulled from active service, it needs a pre-approved place to wait that is secure, observed, time-bounded, and able to produce chain-of-custody evidence. That place is recovery holding. It is not a parking spot and not a depot bay. It is a controlled node where the vehicle sits under known rules while the fleet decides what happens next: retrieval, inspection, remote diagnosis, or law-enforcement hold.
What happens to a robotaxi after an incident or disablement
A disabled or flagged AV cannot just stay where it stopped. Blocking a lane, a crosswalk, or a fire access route creates a safety and liability problem the moment it happens. The fleet's options are to recover the vehicle to a depot, hold it roadside (rarely acceptable), or move it to a nearby pre-approved holding location. Recovery holding is the third option, and for distributed city operations it is usually the fastest and the cleanest.
| Stage | What the fleet needs | What recovery holding provides |
|---|---|---|
| Vehicle flagged or stops | Get it out of the active roadway | Nearby pre-approved destination |
| Vehicle in transit / towed | A confirmed, reservable space | Reservation + access record |
| Vehicle parked and waiting | Security and observation | Monitored, access-controlled bay |
| Investigation or clearance | Proof of who touched it, when | Chain-of-custody evidence |
| Vehicle released | A clean check-out record | Session close + audit trail |
What "recovery holding" actually means
Recovery holding is a defined ground-service function: a private site, pre-qualified and pre-approved, where a fleet can place a vehicle that is out of normal service and keep it under controlled conditions until it is cleared. "Controlled" has four parts. The space is secure (access-restricted, not an open lot). It is observed (camera coverage or staffed presence). It is time-bounded (the hold has a start, expected duration, and retrieval SLA). And it produces chain-of-custody evidence (a record of who entered, when, and what was done).
This matters because a vehicle in recovery is frequently a vehicle under question. It may have been in a collision, triggered a safety event, been struck while stationary, or been pulled for a software fault. Whatever sat in that vehicle's logs is now potential evidence, and where it waited has to be defensible.
Why recovery holding is an under-discussed ground-service need
Most robotaxi planning centers on the depot: where vehicles charge, get cleaned, and sleep overnight. Depots are real and necessary. But depots are centralized, and incidents are distributed across a whole service area. A vehicle that faults eight miles from the nearest depot does not want an eight-mile recovery drive or tow before it is off the road and contained.
Robotaxi service areas now span hundreds of square miles per metro (Waymo operated roughly 315 square miles in Phoenix and a unified 260-plus-square-mile zone across the San Francisco Bay Area in 2025, with combined California coverage around 250 square miles after mid-2025 SF and LA expansions, per its service-area announcements), so even with multiple depots a faulted vehicle can sit several miles from the nearest one. Recovery holding is the layer that catches the vehicle close to where the event happened. The closer the holding node, the lower the recovery latency, the shorter the roadway exposure, and the smaller the liability window. As fleets scale from hundreds to thousands of vehicles in a metro, the rate of recovery events scales with them, and centralized depots become a bottleneck for exactly the situations that are most time-sensitive.
How recovery holding works as a coordinated service
Recovery holding only works if the destination is known and reservable before the incident, not negotiated during it. The flow is reservation-first. The fleet has a roster of pre-qualified holding nodes across the service area. When a vehicle needs recovery, the fleet (or its recovery vendor) reserves a holding slot, the node confirms availability and access rules, the vehicle is delivered, check-in is recorded, the hold runs under SLA, and check-out closes the session with a full audit trail.
XoomPark coordinates that flow. It does not tow the vehicle, inspect it, or repair it. It manages the part that breaks in the moment: knowing which site is available, whether the fleet is allowed to put a vehicle there, what rules apply while it sits, and what evidence proves the hold was handled correctly.
The property defines permission. The fleet validates capability. XoomPark coordinates reservation, access, workflow, SLA, evidence, and audit.
Who needs recovery holding
- AV fleet operators and ops teams (Moove, Avis Budget Group, Transdev-type operators, and in-house fleet-ops groups) who answer for vehicle recovery time and roadway exposure.
- Safety and incident-response teams who need defensible chain-of-custody after an event.
- Recovery and towing vendors who need a confirmed destination, not a phone tree.
- Cities and regulators who want disabled AVs off active roadways fast and held responsibly.
- Parking operators and private-site owners who can turn underused secured space into qualified holding capacity.
Example workflow: a flagged vehicle from stop to release
- A robotaxi operating mid-afternoon triggers a safety fault and pulls to the curb. The fleet's ops console marks it out of service.
- Instead of dispatching a long-haul tow to a central depot, the system queries nearby pre-qualified holding nodes, finds an available secured bay roughly a mile away, and reserves it.
- A recovery driver moves the vehicle. At the node, check-in records the arrival time, the operator of record, and the access credential used.
- The vehicle sits in a monitored, access-controlled bay while the hold runs against a retrieval SLA.
- When the safety team clears it, check-out records who released it and when, and the audit trail (reservation, access events, observation coverage, session timestamps) is available for the incident file.
- The vehicle returns to service or moves to a depot for deeper inspection.

Original research: a taxonomy of recovery triggers and the holding each one demands
Not every recovery event needs the same holding tier. A low-battery reposition needs almost nothing beyond a reservable spot. A vehicle held after a collision is an evidence object and needs the full chain-of-custody stack. Treating all recovery holding as one undifferentiated "lot" is the mistake.
| Recovery trigger | Vehicle state | Holding tier | Secure | Observed | Time-bound | Chain-of-custody |
|---|---|---|---|---|---|---|
| Low battery / charging queue | Operational but depleted | Light hold | Optional | Optional | Soft | Reservation only |
| Software fault | Pulled from active fleet | Standard hold | Yes | Yes | Yes | Access + session |
| Sensor / hardware fault | Pulled from active fleet | Standard hold | Yes | Yes | Yes | Access + session |
| Stranded in active roadway | Disabled in traffic | Rapid hold | Yes | Yes | Aggressive SLA | Access + session + timestamps |
| Struck while stationary | Damaged, potentially evidence | Evidence hold | Yes | Yes | Yes | Full chain-of-custody |
| Collision under review | Damaged, investigation pending | Evidence hold | Yes | Yes | Yes | Full chain-of-custody |
| Vandalism / interior biohazard | Contaminated or compromised | Evidence hold | Yes | Yes | Yes | Full chain-of-custody |
| Law-enforcement hold | Custody-seized | Custody hold | Yes | Yes | Externally set | Full chain-of-custody + access log |
The throughline: as you move down the table, the cost of getting the evidence wrong rises faster than the cost of the space itself. A secured bay is cheap. A contested incident with no defensible record of where the vehicle sat and who touched it is not. Recovery holding is undervalued precisely because the people scoping it price the parking and ignore the proof.
This is not hypothetical. In AV collision investigations the NTSB and NHTSA collect the vehicle's event data recorder and onboard automation logs as physical evidence (see NTSB's automated-vehicle crash investigations and its EDR-data collection practice), and NHTSA's Standing General Order requires operators to report ADS-involved crashes, with the most severe due within five days. Once a vehicle's logs are potential evidence, where it sat and who accessed it is part of the same defensibility question.
Methodology note: this taxonomy is a XoomPark framework for scoping holding requirements, not a published industry standard. It is built to be argued with by AV-ops and safety teams, then turned into per-node qualification criteria.
Not for you (when recovery holding is the wrong fit)
If you run a single fixed depot, your whole service area sits within a short recovery drive of it, and you never operate far enough out for depot distance to matter, you do not need a distributed holding-node network yet. If your fleet is small enough that recovery events are rare and ad hoc handling still works, build that muscle when volume forces it. And if you are looking for towing, repair, or safety certification, recovery holding is not that. XoomPark coordinates the place and the proof. The fleet, its vendors, and its safety team do the rest.
Frequently asked questions
What is AV recovery holding?
AV recovery holding is a secure, observed, time-bounded place where a fleet holds a disabled, flagged, or pulled-from-service robotaxi until it can be retrieved, inspected, or cleared. It is a ground-service function, not consumer parking, and for incidents it usually produces chain-of-custody evidence.
Where does a disabled or flagged AV go after an incident?
It goes to a pre-approved holding node close to where the event happened, not necessarily back to a central depot. The fleet reserves a secured, monitored space, delivers the vehicle, holds it under an SLA, and keeps a record of every access until the vehicle is cleared or recovered for inspection.
Is recovery holding the same as parking?
No. Parking is open, self-serve, and unobserved. Recovery holding is access-controlled, monitored, time-bounded, and tied to reservation, session, and chain-of-custody records. A vehicle in recovery is frequently a vehicle under question, so where it waited has to be defensible.
Does XoomPark inspect or repair the recovered vehicle?
No. XoomPark coordinates the holding node: availability, access rules, reservation and session records, SLA tracking, and evidence capture. Inspection, diagnosis, repair, towing, and the safety clearance decision stay with the fleet, its recovery vendors, and its safety team.
