Berlin and Vienna have spent 2026 turning EU-level pledges into concrete law. The result: manufacturers, garages and mobility services in Germany and Austria must now plan for mandatory data access, new traffic‑data duties and a national AI governance layer — with precise compliance dates that matter to drivers, dealers and suppliers.

What changed this year

At EU level the Commission published detailed guidance on how the Data Act applies to vehicles on 15 September 2025, clarifying that “vehicle‑related services” and the raw or pre‑processed vehicle data they use are in scope and must be made available under the Data Act’s Chapter II rules.

Member states and industry have been implementing those obligations. Austria’s official Digital Austria guidance notes the Data Act’s “access‑by‑design” duty applies to connected products from 12 September 2026 — meaning new cars and services placed on the market after that date must be designed to give users default access to the non‑personal data they generate.

Germany rewrote its national framework for intelligent transport systems (the IVS Act) with an amendment finalised 15 May 2026 and published in the Federal Law Gazette on 20 May 2026; the law designates the Federal Highway and Transport Research Institute (BASt) as the “national body” and sets up the national access point (Mobilithek) for official traffic data.

Separately, Germany put its AI‑implementation law into force on 29 July 2026 to operationalise the EU Artificial Intelligence Regulation: the federal law names national supervisory authorities, creates a coordination hub at the Bundesnetzagentur and establishes provisions for market surveillance and innovation support (KI‑reallabor).

Austria’s wider road‑traffic reform — including stricter e‑scooter/e‑bike rules, camera‑based access management and changes to the legal treatment of e‑mopeds — was approved by the National Council on 25 March 2026; many measures came into force on 1 May 2026, with further rules (e.g. e‑moped provisions) due in autumn 2026. Mobility Minister Peter Hanke called the package “a milestone” for safer, future‑proof mobility.

How regulators are tying data, traffic management and AI together

The three strands — Data Act vehicle guidance, national IVS laws and AI governance — are being linked in practice. The EU guidance and national laws distinguish vehicle data (raw and pre‑processed telemetry) from derived proprietary information, but require OEMs and data holders to provide users and third parties with access under fair, non‑discriminatory terms. National access points and IVS rules mean official traffic and road‑closure data must be integrated into navigation and fleet services.

What this means for the market

Practical consequences start now: cars and services placed on the market after 12 September 2026 will need “access‑by‑design” features, forcing software architecture changes, new APIs and contractual templates for data sharing — a costly but finite engineering task for OEMs and Tier‑1 suppliers (and an opportunity for third‑party service providers). National AI supervision in Germany raises compliance duties for any vehicle function classed as high‑risk AI (ADAS, autonomous‑driving stacks); firms should expect audits, documentation and sandbox approvals. Meanwhile, Austrian cities’ camera‑based access management will shift traffic flows and create new data‑based enforcement use cases for mobility operators.

For dealers and independent workshops the Data Act expands the possibilities for diagnostic and maintenance services but also raises IP and security questions: access to raw data is required, yet manufacturers can withhold inferred/derived information as trade secrets. That balance — and the national enforcement practices that follow — will determine who captures recurring service and mobility revenues.
