If that happened it wouldn't make any difference how or if you had your tanks restrained. Had i said that i had mine strapped in the trunk you would show a rear end collision. If you yad a solution/recommendation could it stand up to the example you posted?
I think some of you are missing the point completely... You take the time to learn, and practice safe diving, but you simply put your tanks, or weights in the back seat? You are risking your life, and others. In the event of a roll-over something simple as a 5 lead weight can kill you. A tank sitting at 3000 psi becomes a missile if the valve is broken off. If you aren't securing your s**t you pose a threat to your self and to people around you.

let me know how that works out if this happens, and it was caused from a blow out, not careless driving:
