<h1>Car-shopping festival raises consumer protection, advertising, privacy (Article 22 automated decisions), antitrust and cross-border data risks for platform.</h1> A leading online automotive platform launched its 2025 car-shopping festival combining digital and offline sales incentives, AI-driven tools, and global expansion efforts. Legally relevant issues include consumer protection and advertising compliance tied to subsidies and prize promotions, data-privacy and algorithmic transparency obligations stemming from deployment of proprietary large-language models and AI decision tools, potential competition and antitrust risks from platform-dealer arrangements and market power in automotive listings, and cross-border regulatory considerations as the platform expands internationally and aggregates vehicle and user data. Monitoring compliance with applicable consumer, privacy and competition laws is advised.
