I still have a scar on my shoulder that I received while riding in the back seat of one of these cars...a 1973 Torino...as our neighbor, coming our way at 70 mph or more, topped the hill in our lane in a 1971 Olds 88. It was white. I still remember seeing its wheels a foot off the pavement as he crested the hill.
I don't know what drugs he was taking, but it was something. My mother, my sister, and I all survived, though my mom's arm was torn up pretty bad.
