Peter took the few seconds he was afforded to step away from the car, not willing to take the chance of being pinned against it. Regardless of this Steve's intentions, it seemed like no matter the universe Cap would always be someone hard to take down and Peter wasn't about to start underestimating his physical prowess or the ability to put on an act.
