Thank you, but that’s a lot of reading for a simple question.
Statistical analysis was by χ2 test; a p value of less than 0.05 was assumed to correlate with a significant difference in rates of injury.
Oh yes it’s all clear to me now.
I know it used to be like that before air bags and safety belts, because the steering wheel takes some of the blow in frontal collisions. But such dramatic difference I suspected she might have made the collision worse for the passengers on purpose.
