Superlative claims at Red Bull Ring — how marketing words become AI-reproduced facts.

An operator writes a superlative on their own page (e.g., "the quietest campsite"). Tourism portals, aggregators, and Booking-style listings reproduce that text uncritically — and it appears as the operator's editorial description across many third-party pages. Large language models (ChatGPT, Claude, Perplexity) crawl those third-party sources, embed them in their training and retrieval data, and return the claim as objective information to consumers. No independent measurement is involved at any stage; the loop converts marketing copy into AI-reproduced "truth".

Section 2 UWG (misleading advertising) and § 2a UWG (comparative advertising) require any comparative claim to reference essential, relevant, verifiable, and typical properties of the compared products or services. A superlative is by definition comparative: "the most X" implies a ranking against all relevant competitors. Without an independent, disclosed comparison basis, the superlative is not admissible as advertising. The Austrian Supreme Court (OGH 4 Ob 4/12g; 4 Ob 174/22d) has confirmed this standard repeatedly.

It does not, acoustically. The Moitzi operator states both claims on the same homepage. But sound pressure attenuates approximately 6 dB per doubling of distance from a point source. At 125 m from the principal noise source (the race track), the direct sound pressure is around 18 dB higher than at 900 m (factor 7.2 distance difference). The independent noise model on gp-camping-guide.com/noise-check/ (ISO 9613-2) makes this measurable. "Quietest" while sitting 125 m from the loudest source in the area is not consistent.

Because Schitterhof's two cited claims here — "900 m walking distance to the Red Bull Ring main entrance" and "night rest 23:00–07:00" — are NOT superlatives. They are objectively measurable facts: GPS coordinates and OSM/Google routing can verify the distance; the house rules document the night-rest policy. The study deliberately does NOT include any superlative about Schitterhof itself ("the most serious", "the quietest", etc.) — that wording is inadmissible under the same UWG logic applied to competitors.

It is the Schema.org-standard wording for a claim that is not necessarily false in itself, but where essential context is absent for a consumer to assess it. Superlatives without a disclosed comparison basis are the canonical Missing-Context case: the claim cannot be disproved by a single counter-fact, but neither can it be verified — it is published into a vacuum.

No. The study cites verbatim what each operator publishes on their own pages, attributes the source and capture date, and applies a Schema.org ClaimReview rating strictly to the wording's testability — not to the operator's commercial intent or the actual quality of their facilities.
