In effort to slow speeding drivers whooshing downhill, Hayward has installed novelty traffic signs whose WTF-ness does more to alert drivers and pedestrians than the more standard admonitions do. Wacky, pictogram-heavy signs with messages like "Downhill: Use eyes, brakes, brain" and "Heads up! Cross the street, then update Facebook" have, so far, packed a surprise factor that causes people to pay attention, if only to get a better look at the sign and, probably, post it to Twitter.
