Crooked as an Arrow

On a lovely day out in Lichfield with my beloved, we happened upon this sign that made us smile. I've never seen such a wonky arrow before.  Maybe a rogue badger hurls itself at delivery vehicles, causing them to swerve and what exactly are drivers supposed to do when they encounter the giant rectangle?

But after noticing some of the higgledy piggledy old houses of Lichfield, maybe the wibbly arrow is just in keeping with the rest of the city.
