Bradley grows up in the front seat of his mom's car and in the backseat of his uncle Tom's - soon to be called Pops - car. If Mav had a driver's licence, he would probably have sat a little here and a little there. It becomes part of his universe, and Bradley will end up cherishing every single conversation he had with both of them while they were driving. He won't get the chance to drive his mom around, to young to even reach all the pedals, but he is going to be old and capable enough to drive his pops to the hospital and back every time he needs to, and he will confine dad in the back because he made the mistake of having him in the front once and he got this close to stopping and leaving him miles from home.
At some point, it becomes pretty normal for Ice to sit on the back with Mav just so they can have a conversation, all three of them, with Maverick translating Ice's sign language.
