What shipped
Drag the handle across the three states. On the left is what riders had: every screen announcing its own status — ride booked, Lyft requested, searching for nearby drivers — and a countdown running down to nothing. On the right is what shipped: one screen across the whole wait, giving a range while the estimate is still a range and narrowing it as the car gets close.
Cancel rates fell 10% in the learning period and 4% on switching, and because it shipped as a framework rather than a screen, scheduled rides and airports built on it.
