Designing Driverless Cars for Everyone (Not Just Early Adopters)

Driverless cars can pass every safety test and still lose the passenger — because trust, not technology, decides whether robotaxis actually scale.

Dr. Clare Mutzenich on the human factors inside the autonomous vehicle almost no one is designing for.

Most coverage of autonomous driving is about the driving. This conversation is about everything else — what happens inside the cabin of an empty robotaxi when something goes wrong, and who's in charge when there's no driver to turn to. Dr. Clare Mutzenich is Professor of Human and AI Interaction at Loughborough University and founder of Anthrometric, an independent human factors and behavioral science consultancy. She's spent a decade studying self-driving safety, remote operations, and how real people actually behave inside these vehicles.

We get into the many layers of passenger trust, why the human driver was doing far more emotional and social work than we credit, and what her 91-person VR emergency study revealed — including the finding that nearly everyone, across every demographic, wanted the same thing: a button to a human.

We also cover accessibility when the interface becomes an AI, the realistic limit on how many vehicles one remote operator can supervise, the UK's Automated Vehicles Act 2024, and why Europe's slower, more cautious approach might be an advantage rather than a handicap.

Recorded as the UK prepares for its first driverless taxi services — so the timing matters.
