Robotaxi operators are confronting an awkward design problem: riders treating autonomous vehicles as private spaces for sexual activity. A recent workshop, "Love in Traffic," brought together researchers and industry representatives in Sweden to consider how interior design and technology can curb this behavior. The discussion follows reports of people having sex in Cruise robotaxis and a separate incident in which teens drank and shot gel beads from a Waymo, illustrating the risks of riders assuming more privacy than the vehicles actually provide.
Human factors researcher Alexandros Rouchitsas, one of the workshop organizers, said there are two prevalent use cases: opportunistic content creators who see robotaxis as cheap, well-lit studios, and tourists unfamiliar with local norms. Cultural differences add urgency, as operators in the Middle East and Asia face legal frameworks far stricter than those in the US. In some markets, riders do not even book the whole car, meaning strangers may share the cabin.
Design solutions discussed include making seats transparent, removing curtains, and using occupant monitoring systems to detect intoxication or risky behavior. Rouchitsas suggested AI assistants could act proactively, warning riders when they cross a line. The underlying message, he said, is that privacy in a robotaxi does not mean behaving as one would in a bedroom; public displays of affection should follow workplace rules. Waymo and Zoox did not respond to requests for comment on how they discourage such behavior.
