A system may attribute an event, which occurred during an operation of an AV, to one or more AV behavior changes through backtesting of the AV software version. The system may identify one or more critical events from events detected by the AV based on classifications of the events. A critical event may be an event that impairs a performance of the AV. The system, after identifying a critical event, may run backtesting of the AV software version. The system may simulate AV operations, which are controlled by the AV software version and one or more historical software versions, in a virtual scene generated based on the critical event. The system may determine whether there is a regression in the AV software version based on AV performances in the simulated AV operations. The system may determine one or more AV behavior changes based on the regression.
