If that one works for you that ' s cool . I ' ve read some comics that explain when Barry runs he doesn ' t even need to think about it and it ' s like his body is running on its own , which allows him to have a clear mind to think about things , so some reflex explanations are a bit tough for me to swallow . While trying to find some other people ' s explanations for it I stumbled upon Barry thinking he ' s too fast for everything , and so he ' s too cocky to use even a fraction of his actual speed on his weekly villains . This explanation kinda fits thematically for Barry and doesn ' t make me wanna bitch and moan when Barry gets hit by simple shit not implying your explanation makes me bitch and moan , just saying in general .
