Not trying to sound morbid or anything but the most recent news article about the crash states the investigating police said the Cobra was travelling "about 70 mph" in a 45 mph zone. I have to believe the authorities have a pretty good feel for the speed factors involved for both cars.
So, 70 mph in a 45 zone is the same as doing 116 mph in a freeway 75 mph zone. ( 77.777 percent of twice the posted speed limit).
Makes me wonder about lots of things - i.e., reaction time, controlability, stopability, visibility, to name a few.
