I'm not having a go mate, you've held your hand up pretty quick and I respect you for that: Many wouldn't.
Yes, we take our cars to track to push them, but it's quite clear neither you, the car or the track were ready for that, so you should've eased off. Instead, the red mist came down and you were lucky to walk away, as Jetpilot says that's a dangerous corner at the best of times.
Was that your first track experience?
