Looking for Trouble: Pre‐Intervention Monitoring in Human and AI Driver Training
Symbolic Interaction, EarlyView.We compare two types of situations involving monitoring of car driving: a driving instructor overseeing a trainee driver and a safety driver overseeing the performance of autonomous vehicle (AV) software. Our focus is on instances of monitoring that precede (1) interventions that are aborted before impacting the driving and (2) actual interventions on ...
