A lady I used to work with had a Civic when she was pregnant ~50 years ago. She went in to give birth to her kid and two popped out (no routine ultrasounds in those days). No big deal, they both got tossed in the cardboard box in the back seat. A few blankets and they were ready to go. Modern car seats obviously provide better protection, but they are getting so damned large many/most are impinging on the drivers seat. With smaller cars, this makes the problem even worse.
Older cars also had much larger interior dimensions relative to exterior dimensions (less crash protection, less stupid design, less huge plastic trim).
