A friend told me about a little pre-schooler he knows who kept talking about "the truck with the arrow on it." Nobody could figure out what he was talking about, then he pointed to the FedEx truck... and still nobody could figure out what he was talking about. But guess what: the kid was right. Can you spot the prominent arrow in the FedEx logo. There's no doubt that this is an intentional design element, and one which is brand aligned.

Great design, even when nobody (consciously) notices.
