Family driver
Jethro always drove the car? Anyone recall Uncle Jed driving?
Was Jethro driving legally?
It was inconsistent about who could drive. In the B&W episodes Granny apparently COULD drive, I remember an episode where they were on a double date and Jethro and his girlfriend got left behind somehow, and Granny drives the truck back home with her date in the passenger seat. Then Granny drove her and Elly to the bank once, BUT in later episodes Jethro was trying to teach Granny to drive.
I think Jed was once stirring while Jethro pushed the truck when it broke down once.
