Maybe these ads make nnno sense to anyone who is not Lebanese. But they are doing is that they are associating Pepsi with drivers' behavior. "Don't overlap on anyone's lane, stay chill" or "even if there's a bottleneck (traffic jam) stay chill" - the visual only emphasizes the visual connection either with the straws or with the bottle caps. As I said, perhaps a non-Lebanese would not get it, but locals will. Now, if they remain chill or not is a different story altogether.
