Optical speed bumps

In West Vancouver a new optical speed bump is being used that makes it look as if a young girl is darting out in front of the driver's car. I can't imagine this is a good idea because once people realize this is just a trick, they'll stop slowing down when they see children in front of their cars. Of course then again this will turn every child in Vancouver into a literal speed bump, so maybe there's an upside.
