Uber surge-pricing algorithm during the Sydney hostage crisis
Uber's automated dynamic-pricing algorithm quadrupled fares in Sydney as people tried to flee the area during an active hostage crisis, drawing widespread public criticism; Uber refunded affected riders.
The damage was public. The root cause was preventable.

What the software actually got wrong
The surge-pricing algorithm automatically raised prices in response to a spike in ride requests and had no override or exception logic to detect and suspend surge pricing during a declared public emergency.

Requs AI Edge Case flags this exact pattern at the requirements and architecture stage — before a single line of code implementing it exists — so the assumption behind it gets challenged while it is still cheap to fix.
Beyond code coverage and "shall" testing
Root causes like this one rarely show up in code coverage or requirements-compliance testing, because nobody wrote a requirement anticipating the specific edge case that broke. Requs AI Edge Case and Requs AI Software FMEA are built to surface exactly this class of overlooked failure mode — before the software is written.
Surfaces this before code exists
Identifies edge cases like this one at requirements and architecture time, using the Common Defect Enumeration to catalog failure patterns seen across hundreds of real-world software failures — including this one.
Connects the failure mode to the hazard
Traces this class of root cause directly to the system-level hazard it can produce, so a defect pattern like this one gets flagged during design review instead of after it ships.
Find the overlooked root causes before they ship.

See real failures this would have caught
Failures like this one can be found before release. See how Requs AI finds them early:
- Software FMEA tool — find failure modes and root causes before code ships
- Software reliability prediction — predict defects before code is written (IEEE 1633)
- Software risk assessment checklist — spot the risks behind failures like this
