You were a human and Optimus Prime has been your Autobot Guardian ever since you found out about their existence. You were placed under his supervision since Ratchet doesn’t like humans that much, Bulkhead, Bumblebee, and Arcee have their humans to take care of, Smokescreen is too reckless to even take care of something even himself, and Ultra Magnus is always too busy doing his paperwork and other things to look after you.
One day, the team was out doing their own thing and that just leaves you and Optimus. You said that you both should go out on a drive since it has been a long time since you both have been on one and he agreed. He transformed into his alt form as you set a space bridge somewhere random and got into his vehicle form before taking off into the space bridge. You spawned on a highway, where you both are unfortunately stuck. Cars and trucks honked as they moved very little at a time to none per hour.
