My understanding is ole Governor “Crash” Corzine wasn’t wearing his seat belt either.
I signed my letter “Speed Racer”, and I challenged the Guv to a race when he gets better.
His injuries are consistent with being thrown up against the dashboard/windshield. Either the airbag didn't deploy because there was insufficient front impact, or it had been inactivated.
It's pretty easy to tell if somebody was wearing their seat belt/shoulder harness in a high speed crash --- they have a beautiful set of bruises across their hips and on one shoulder.
