I went airborne in an old Dodge Dart like that in the '70s with my maternal grandfather. The way back to our house in Spring, TX you had to go up and over the railroad tracks and make an immediate left. My grandfather turns to me to ask where to turn and we launched over the RR tracks. I was pointing to the left as we flew right by the turn. Both of our heads touched the roof. We agreed to not discuss the issue with anyone and kept that to ourselves.
