Without debating or arguing, who do you think wins? Just curious.
Also, the grapple gun itself probably has the tensile strength and a powerful-enough spring to pull the car if used as a harness and hooked on to something.
Logically, Batman could possibly take this. Not because he has better feats, but because of his gadgets and weapons, in my opinion. That electric gun (forget the name) and those electric gauntlets he had in Origins could give him the win, since Vibranium in the MCU conducts electricity, rather than insulating it. The part about Batman blitzing spec ops guys is cool and all, but blitzing normal humans doesn't mean he can blitzed enhanced humans. Speed is relative. Batman might be fast to them, but it doesn't mean he could be fast against Black Panther. At the same time, Panther may not have a significant speed advantage against Batman here, either.
