Track accident

One of the wierdest accidents was @ Tulsa Raceway Park a few years back.
An upcoming woman (Shelly Howard) drag racer in a top fuel dragster, was testing @ TRP.
She left the starting line, got crossed up mid track.
The car got turned around & came back down the track (under full throttle) towards the starting line.
She ran into her support rig, killing her & her son.
Very tragic.
Safty is there for a reason, abide by it.

That's horrible. Maybe I'm missing it, but, what safety regs did she violate? Sounds like she was passed out and her foot was wedged against the gas or something?
