Plot hole: Lois Lane and other people see Clark Kent unhurt when a taxi hits him and suffers damage, but don't draw the obvious conclusion that there's something extraordinary about him.
Athletic JasonSuggested correction: I always took this as an intentional jab at how the people of Metropolis, and Lois in particular, were so oblivious to the fact that Clark was obviously Superman. Still a plot hole, just an intentional one.
