I don't know what happened (none of us do) but its probable that to have such a talent failure in such a high calibre car, his mate may have been showing off and come undone.

Don't mess around with other peoples lives in your hands on the roads. There's a place and time.

I hope he was killed on impact, and didnt have to endure a firey death, cant think of a worse way to die.

RIP Mate, you will be missed.
