FA-85678 / Ride-hailing fare and surge pricing / Member archive

Partial pickup minutes not compensated · case 03

Drivers get nothing for the first 59 seconds beyond the time threshold.

Member previewVariant 3 · 3 implementations · 7 checks per implementation

Case contract

A long-pickup fee compensates drivers for pickups beyond thr_m meters and thr_s seconds. The distance part is per_km on meters beyond thr_m (prorated, half up); the time part is per_min on each started minute beyond thr_s; each part uses only its own positive excess. The total is capped at cap cents.

Why this case matters

Ride-hailing prices are computed per trip at scale; ordering, unit and boundary slips become systematic over- or under-charging.

One recorded failure
