I was born in 58, road in the back window of the Buick after the last wagon. Road in the back of a 61 Falcon wagon from Iowa to Wyoming with the rear seat folded down and the back loaded level to the Windows. There was a time on the trip that the rear window was down and I tossed something of my sister's out the window.
Around town we would sit up front and get the arm across the chest to keep us in place for a quick stop.lol
Ah the good old days!
