## Engineering risks to plan for
!High complexity for short timeline - real-time features and payments need extensive testing
!Safety and liability concerns in P2P transportation require legal consultation
!Route matching algorithms may need multiple iterations to work effectively in Indian traffic conditions
!Payment splitting with UPI has regulatory compliance requirements
