I well remember standing up on the front seat of my Father's 1947 Pontiac when very small. My Father would reach over with his right hand to hold me if he had to brake hard. Later, when a bit bigger, I would stand on the floor.
If all of us were in the car, my two brothers and I would stand on the floor behind the front seat and hold on to the strap attached to the back of the front seat.
Later, I taught myself to drive and wrench on that 1947 Pontiac.
Merry Christmas to all!
