The driver of a Koenigsegg CCR lost control of the Swedish supercar at 2013 Gran Turismo Polonia event and seriously injured several spectators.
In the second video below you will notice right from the start the driver doesn't have the skills to tame the CCR as he loses control of the vehicle immediately after being green-lighted. GTBoard.com is reporting the driver decided to disable traction control which clearly was a bad move. The outcome of this crash: four spectators were seriously injured, while an additional 15 were also affected.
On a side note, if the Stig crashed a CCX during Series 8, Episode 1 of Top Gear UK, clearly an amateur driver like the one in this yellow CCR should keep traction control on at all times.
Thanks to Robert for sending us the tip!
