And thus, Churchill was nearly killed.
(True story: in 1931, Churchill visited New York, didn't look both ways before crossing the street, and was knocked down by a taxicab.

He survived (obviously). But what if he didn't? Then Britain would've been led by Lord Halifax in 1940, and might have stayed out of WW2 -- since Halifax, in real life, was willing to explore a negotiated peace with Hitler in 1940. (To give Halifax his due, once war was declared, his desire for peace was overridden by his distrust of Hitler, and he gave Churchill his full support).
And that's another reason to look both ways: if you do, you might save Western Europe).
