Locals get used to whatever they encounter regularly. I know which humps are rough & which I can cruise over on my regular route.
Also, distracting drivers as they approach a pedestrian crossing is a really bad idea. This optical illusion will distract drivers from checking for approaching pedestrians.

@joland @TDCN it's the same as if you crash a borrowed car while doing something that invalidates the insurance, eg racing.
