Passenger Pickup ambiguity

[TSampley]

We want to track when 1) the driver arrives at the pick up location as well as 2) when they begin travel to the passenger destination. These should be separate events; ideally they occur within seconds of each other: the provider arrives at the pick up location and the passenger enters; the provider then confirms the ride start. In the worst case, the provider may arrive and need to wait for the passenger to arrive.

• Problem: Arrival confirmation and Trip start confirmation may be annoying to Providers
  • Solution: Origin arrival event could be automated by GPS proximity to origin
    • Problem: Temporary loss of GPS accuracy could prevent registering provider arrival
      • Solution: Provide button to manually progress to arrived state
  • Solution: Origin departure event could be automated by accelerometer and/or GPS
    • Problem: Same as above - temporary loss of GPS accuracy could prevent registering provider departure a.k.a. trip start
      • Solution: Provide button to manually progress to trip started state
        • Problem: Provider would be moving at this point - distracting from driving; minor concern?

We cannot account for all potential issues; we need to determine the most reasonable cases to support.

• Problem: Passenger phone has died
  • Solution: Automatically cancel trip request after some time with no communication from passenger
  • Solution: Continue with trip since all necessary interaction is on Provider-side; allow Provider to cancel if necessary
• Problem: Passenger is not at pick up location
  • Solution: Driver can message passenger
    • Problem: Passenger is not able to reach location (in timely manner or at all)
      • Solution: Driver can cancel trip
  • Solution: Reference passenger location
    • Problem: Passenger GPS is not working
      • Solution: Driver can message passenger
        • Problem: Passenger is not able to reach location
          • Solution: Driver can try to find passenger
            • Problem: Expects driver to potentially go on wild-goose chase for ornery passengers

We expect the passenger to be at the agreed/confirmed pick up location.
