not just a car. I didn't get hurt at all, not even shaken. Seat belt held firm; back of the seat supported my head. People in truck are yelling neck & headache, of course. I was surprised the air bag didn't detonate. I laid down on the brakes, but still hit it pretty hard. It felt like it took about 30 minutes to impact, and I kept thinking down to the last millisecond I'd be able to stop. No. Got a truck load of groceries all over the hood of my Z.
