Which side of the road do they drive on? (Part 4)

They must have had trouble with this in London, because they write it on the pavement!  At busy intersections they write on the pavement just as you would step off the curb “LOOK LEFT” or “LOOK RIGHT” along with an arrow. 

In fact, the crossing system is different at many of the spots.  There might be a crossing section with an island in the middle that is marked by round yellow globes.  Cars are supposed to be alert, and pedestrians are supposed to be alert, without a light to control it.  It seemed to work out fine.
