• Real-time location tracking during rides
• Dynamic pricing based on demand
• Rating system for drivers and riders
• Payment processing and fare splitting
• Ride history and receipts

Non-Functional Requirements

• Match riders with drivers within seconds

• Handle millions of concurrent rides
• Location updates every few seconds

Questions to Consider

• How will you efficiently find nearby drivers?
• What algorithm handles supply-demand matching?
• How do you handle location updates at scale?
