## AI overview

Google Research examines whether hard-braking events collected through Android Auto can indicate crash risk on road segments. Combining anonymized, aggregated hard-braking data with public crash records from California and Virginia, the study finds a statistically significant positive association and identifies hard-braking events as a denser, potentially leading measure for road safety assessment.
