Analysis of Field Effects Associated with the GM Super Cruise System

Abstract

This effort examined the field impact of the Super Cruise system on lane departure crashes and “quasi” system-relevant rear-end striking crashes. Two statistical approaches, binomial exact tests and a quasi-induced exposure logistic regression, were used to explore the limited data available more thoroughly. The Super Cruise-equipped vehicles used in this analysis were Model Year 2018-2020 Cadillac CT6 sedans and Model Year 2021 Cadillac CT4, CT5, and Escalade vehicles. Matched Model Year 2016- 2021 vehicles were used as comparison fleets. These fleets were matched to police-reported crashes from 12 states. In light of the widespread lack of statistical significance across the variety of analysis approaches employed and the large number of statistical tests conducted, there is currently no evidence for a difference in system-relevant crash risk for Super Cruise-equipped vehicles compared to matched highly-ADAS equipped vehicles without Super Cruise. Continuing to revisit this Super Cruise field analysis with additional crash data and miles driven should continue to improve our ability to evaluate the effect of Super Cruise on system-relevant crashes in the future.
