I am really surprised this didn't kick up

I'm reminded of a wrongful death trial that I was on some 25 years ago or so.
I opened my big mouth in deliberations and the ladies made me jury foreman.
By the time of the trial the death car had already been crushed and was not available for examination. It was an older car of some type. Late 70s I think.
Still, the expert witness for the plaintiff made conjecture about what speed the other car was traveling when it hit the death car.
The trial did not end in the plaintiff's favor.
We all make assumptions every day to get through life.
