Am I not the only one that would ask how in the heck the camera can clearly see SEWELL and not the plate letters 4x the size?
They aren't any clearer. Your brain resolves Sewell because you recognize the formatting and pattern and then it resolves the letters for you.
Unfortunately, you need a specific camera system to fully resolve plates, but as everyone said, it won't matter, those plates aren't legit or they are stolen as well. You don't break into a truck by sliding up in your excalade and steal it in under a minute because you are new to the game.
OP, you might be able to resolve more plate frame by frame. The G is decent in that shot but a previous frame may have more info if you have the luxury of access.
