They were driving the Wrong Direction on Track, so the opening in the Guard Rail wasn't protected. The Instructor was a Lead Instructor and should have known better. As an Instructor, I try not to take extra chances with my life and an unsafe Track is one of my No-No's. I also don't right-seat coach anymore.
The Petty Experience allows too many guys with a pulse - they offer no Health Insurance, No Benefits, etc. The Disney Track was going to close in a couple of months anyway - I could see the whole Petty Experience going away too after this.
