GAIA initialises interactive scenarios directly from unstructured real-world video, and GRADER, an offline component independent of the driving stack, learns geographically specific driving conventions from data without being given road rules. Statistical evidence transfer uses Bayesian power priors to formalise expectations of consistent event rates. The payoff Wayve claims is large: leveraging customer fleet data reduced the 95% upper confidence bound on the estimated event rate by a factor of three, and reduced the required validation data by more than 20-fold.
