How far has each regulatory function normalised automated driving, and which legal bridge or gate manages the mismatch between layers?

Snapshot 2026-09-05 (frozen)Rows 12Coder JADOI not yet mintedSource dataset Layer Coding – AV Historydata.csv · data.json

Each regime is a vector of seven layer states, not a single maturity score. Read across a row for the configuration; read down a column to compare one function. The five 2026 regimes do not line up on one common ladder: they display different layer configurations and different leading layers, and the legal bridge or gate that manages the interface between a leading and a lagging layer differs in doctrinal form even where the pathway repeats.

Draft law is excluded from current-law scores and shown separately as sensitivity evidence. The historical United Kingdom panel (1861–1930) applies the same coding to the normalisation of the motor car and is published as a separate snapshot of this module.

N0–N4 ordinal coding of seven functional layers per regime; range and asynchrony as descriptive signals of inter-layer asymmetry; pathway families as recurring configurations. Scores measure legal embedding, not regulatory intensity, and are never aggregated per jurisdiction.

Dominant legal bridge / gate Exceptionalisation through special operational constraints Important caveat Liability and infrastructure coding is based on absence of demonstrated technology-specific integration, not absence of general law.

Dominant legal bridge / gate Exceptionalisation / precautionary direct-control regime Important caveat Do not equate restrictive regulation with low regulatory activity: N1 denotes bounded accommodation, not deregulation.

Dominant legal bridge / gate Regulatory recalibration Important caveat Infrastructure is coded N1 because the regime reacts to roads/bridges but does not yet evidence system-wide infrastructural institutionalisation.

Dominant legal bridge / gate Classificatory bridge: light locomotive ‘deemed to be a carriage’ Important caveat N2 does not imply comprehensive motor-vehicle law; it denotes transitional/intermediate integration. The classificatory bridge is coded separately as the mechanism supporting that state. Confidence High Core ROAT records ROAT-2026-0267 ROAT-2026-0268

Dominant legal bridge / gate Dedicated licensing/registration institutionalisation Important caveat Driver licensing was initially identification-oriented rather than a mature competence-testing regime; N3 reflects dedicated legal institutionalisation, not full substantive maturity.

Dominant legal bridge / gate Mutual-recognition / certification bridge Important caveat The liability score reflects the UK/European motor-risk environment rather than obligations created by the 1926 Convention itself.

Dominant legal bridge / gate System-level institutionalisation and risk pooling Important caveat N4 is not deregulation: the mature system is more institutionally dense than the 1865 regime.

Dominant legal bridge / gate Equivalence/exemption + compatibility bridges Important caveat 2018 is used as an analytical baseline; Regulation 2018/858 applied later and the score reflects the emerging architecture rather than one single commencement date.

Dominant legal bridge / gate Agency/deeming bridge + dedicated technical institutionalisation Important caveat Article 34bis entered into force on 14 July 2022; it does not designate the ADS as the legal driver and does not create uniform domestic operational law.

EU 2026/481 moves automated parking toward unlimited-series market access. Dominant legal bridge / gate Dedicated technical harmonisation + persistent operational bridges Important caveat Technical approval is coded N3 overall because N4-like unlimited-series treatment currently applies to a narrower automated-parking sublayer, not to all ADS deployment.

Caveats

The Source dataset records no coding date per panel; snapshot_date is the export date. Modern rows (2018–2026) are coded against the sources listed in each row.
Historical scores are based on the presence or absence of technology-specific integration in each layer, not on the density of regulation.
Longitudinal EU/UNECE and Great Britain rows overlap with the 2026 cross-section and may differ by one stage where the coding rule was applied more strictly in the cross-section.

Findings recorded with this panel

Finding	Empirical implication	Article use	Status
Historical peak asymmetry around 1903	Operation, driver/actor and behavioural rules reach N3 while liability/infrastructure/international recognition remain N0–N1.	Strong evidence that normalisation is not one transition; the regulatory system can be highly developed in some functions and rudimentary in others.	SUPPORTED – first-pass coding
Historical convergence by 1930	The layer range narrows as liability/risk pooling and system-level road governance catch up.	Supports defining normalisation as convergence toward stable embedding, not deregulation.	SUPPORTED – first-pass coding
Modern EU/UNECE technical lead	Technical approval and international harmonisation are N3 while operation, actors and infrastructure remain N1–N2.	Direct empirical support for layered/asynchronous normalisation and the dual-pillar claim.	SUPPORTED – current 2026 sources
Great Britain shows law can lead implementation	Dedicated actors and responsibility rules reach N3 before full operational authorisation and final safety principles are in force.	Important falsification of a simplistic pacing problem: asynchrony is multidirectional, not merely technology-fast/law-slow.	SUPPORTED – current 2026 sources
Legal bridges cluster in high-asymmetry periods	1896 reclassification, EU Article 39, Article 34bis and UK passenger permits appear where one layer needs to function before adjacent layers are fully institutionalised.	Supports treating legal bridges as mechanisms for managing inter-layer mismatch rather than as isolated drafting techniques.	PROMISING – requires broader case test
