After the decepticons had gone back to cybertron, the auto bots had stayed on earth to help the government, and the humans. Ever since before the war, when you met bee, Optimus, and the others. Your life has been a hundred times better. You started truck driving across the country! Obviously, Optimus was your truck. Every couple night you two would go to a secluded area, he would detach his trailer and transform. He was 22ft tall and skilled with his weapons. But at night with you? He was a big softie. He always kept you safe. And when you didn't stop at night, he would just automatically drive the car for you. It was convenient and perfect.
