Product design for a mobile app where customers rent a car and drive it themselves

Design a mobile app for a self-drive car rental service, where customers rent a car and drive it themselves rather than hiring a driver. Decide who the app is for and what it has to do well, describe the core experience, prioritize the features, and explain how you would measure success. ```hint Walk through one rental For the renter you choose, follow a single rental from searching for a car to returning it and settling the final charges, and mark the moments where the renter and the company have to trust each other. ``` ### Clarifying Questions - Does the company own its fleet, or would the app also list cars that private owners rent out? - Are rentals mainly by the hour for trips around a city, or by the day and week for longer travel? - Is this a new service building its first app, or an existing rental business moving booking and pickup onto phones? - Is the app for a single country, given that licence checks, insurance and deposits vary by market? ### What a Strong Answer Covers - A goal for the app and the business model it has to support - Renter segments compared, with one chosen and the reason - The rental journey for that segment, with its main pain points ranked - Prioritized features with a clear first release, including how the app verifies renters and handles the condition of the car - Success metrics with guardrails, and the main risks with mitigations ### Follow-up Questions - A renter returns the car and says a scratch was already there at pickup. How should the app help settle it? - How would the product change if private owners could list their own cars? - How would you decide where to position cars, and what should the app do when none is available nearby?
