Sadly, from the descriptions, I would bet on the Vette being the cause factor.
Cars like the Corvette have such high limits, they can make an “average” driver feel like they can do anything. Sadly, this is as far from the truth as you could imagine. It just means that when things go wrong, they REALLY go wrong.
I’ve answered many of these calls during my former career. Always a tragic scene, always such unnecessary death and suffering.
For the dead, thier suffering is over. I have nothing but sympathy for the innocently injured and the surviving family of the dead....
