The Italian driver of this 458 Spider had only just picked his new car up and was driving it for the first time in the rain and faffed about on a slip road, so someone in a saloon (with Ferrari seat belt covers) overtook him.
The 458 driver saw red (well he was in a Ferrari) and tried to take his place back, lost the rear and smashed into the barrier. Happily no one was injured. Also happily it was all captured on camera.
