I remember oldsters complaining about the lack of room in the back seat of cars in the 50s & 60s. While in college I rode home in a Dodge/DeSoto/Chrysler four door from the early 40s. You could not touch the front seat with your feet when sitting in the back seat.
I think I’ve never have been in a 40’s car but I remember cars being tanks.
Probably got ten miles a gallon but I remember gas at 31 cents/gal
