Crazy accident at a track

Moparofficial, I was thinking the exact same thing! What a douche...
I got 3 questions:
why did black car stop? (maybe it was burnout stage...probably after writing this)
where did green car end up...did wall actually stop him?
did safety SUV do a burnout responding?

almost seems like something like this would mandate a remote deadmans switch protocol like Monstor trucks use to prevent runnaway accidents. Safety official has a radio controlled kill switch.
