Did your rescue dog fall asleep in the car driving to his new home and why?

If you adopted a dog from the pound or other noisy or dirty place did he fall asleep on the way home and, if so, why?
I remember one we adopted, an Australian Shepherd puppy, who just chewed on the leather on the door. But when we let him out onto our four acres he couldn’t stop running all around our house. It was great. This was in 1972.
