I realize that this is very far from being an important issue, but–all the same–it is something that has always puzzled me when I watch movies from the '40s, '50s, and '60s:
Why do they always seem to show drivers entering their cars from the passenger side and then proceeding to slide across the seat?
My experience with cars goes back to the '50s, and, except in very rare instances, I don’t recall any drivers in the real world getting into their cars via the passenger side door and then sliding across the seat. The only exceptions I recall were situations where the driver’s door couldn’t be opened as a result of a snowbank or other obstruction.
And, of course, the advent of bucket seats in later years made this type of maneuver almost impossible, but why was this shown as typical behavior in movies of a few decades earlier?
