There was MUCH more walking back then as well.
I was the baby, born in 1947. My oldest sibling was born in 1940. We never had a car growing up. We walked or took the bus. My second-oldest sister born in 1942 bought the first car in the family, probably sometime in her 20's. My brother was next after he was discharged from the Army in 1968. His first car was a red Camaro.
