It really really wouldn't have been.
Those statistics showing that big SUVs are more dangerous are achieved by crash tests that involve the car driven at a child sized test dummy - standing up in front of the vehicle - clear space beyond them.
In such tests SUV's tend to be more dangerous as the kid gets knocked down and pulled underneath.
In smaller vehicles that same standing child would go over the bonnet.
These tests are also done at lower speeds, above a certain speed point, it doesn't really matter what vehicle hits you, you're likely to die.
However in this case the vehicle went through a fence and hit a table full of SEATED children and almost immediately into a solid wall, the side of the school.
ANY vehicle in this case, would almost certainly have killed whoever was in its path, child or adult.
As for the poster stating 'if she ever gets behind the wheel of a car again....'
You'll do what? Exactly?
Make a criminal of yourself I assume?
Because if she does it'll be perfectly legal I am sure, along with the myriad other people with stable, treated epilepsy, who drive. Are you going to threaten all of those people too?
