High-Level Design
Design Uber / Nearby Drivers · Part 2
Problem context
Design the core of a ride-hailing service: drivers continuously report their location, and when a rider requests a ride, the system finds nearby available drivers and matches one.
In scope: location updates, finding nearby drivers, matching one without double-booking, and driver availability. Ride state, payments, and the trip lifecycle are a separate stateful service.
What a strong answer sounds like
State the decision, connect it to a requirement, and name the tradeoff. Keep the design focused on the workload in the prompt.
