Rally Argentina in the 2001 WRC. Up on a stage, 10 spectators cars were caught up in a fire. Cue the emergency services to head out to the scene. Unfortunately, one water tanker clipped a Skoda team member on the way and rolled, severely damaging both Skoda WRC cars. No one was seriously hurt but Skoda pulled out, understandably so.
None of walls prone to being hit are particularly easy to move back though.Suzuka has had a seemingly large proportion of colossal accidents recently. Runoff lengths and upgrades probably required Tbh.
