According to the Southern California Timing Association website, which hosts the event, the weather was good and there was no wind on November 10, so it isn't clear what may have caused the crash. Despite the car being destroyed (including the entire front end being sheared off), Gillespie suffered only "minor injuries" and is recovering. The SCTA site does state that Gillespie managed to crack the 320-km-per-hour mark in a previous run with a top speed of 323 km/h, so congratulations to him on that!
