    Step 1: Problem Statement Analysis (Uber)

    Core Product Features

    A ride-hailing platform must support:

    1. User Profiles: Distinct accounts for Riders and Drivers.
    2. Vehicle Management: Registering vehicle models and documents.
    3. Real-time Dispatching: Matching a Rider's request with the nearest active Driver.
    4. Trip Tracking: Logging trip status (Requested, Accepted, Arrived, In-Progress, Completed, Cancelled).
    5. Dynamic Fare & Payments: Calculating fare based on distance, time, surge, and routing transactions.

    ️ Key Technical Challenges

    • Geospatial Query Bottlenecks: Tracking real-time driver coordinates (lat/long) and fetching drivers within a 3-mile radius in milliseconds.
    • High State Mutability: Constant trip updates (Driver coordinates, ETA, ride status) require rapid database operations without transaction locks.

    Business Rules

    • A driver can only accept one active ride request at a time.
    • A rider cannot request a new trip if they have an ongoing trip in progress.
