Proof of Usefulness Score
Category Standard

Zipcar is a verified, established market leader in the car-sharing industry with high real-world utility and massive global reach. However, the specific project submission provided is of low quality, containing inaccuracies (e.g., 'nonprofit' tag) and lazy copywriting. The high score reflects the verifiable reality of the Zipcar business (hundreds of millions in revenue, global user base) rather than the quality of the form entry. The technical innovation score is moderated by the maturity of the solution and the competitive landscape.
