Pavement marking. Why and What for

I have spotted this "design-flop" in Madrid. Actually it might not be that much of a flop. If we ask why this pedestrian crossing is like this we would find several explanations. A very plausible explanation could be that a car was parked when the paint crew arrived.

In many occasions rather than asking why it makes better sense to ask what for. In this case the unorthodox design of the pavement marking allows for one extra car to be parked in the street. And some paint savings too.

A simple design mistake can trigger a call to 911. Such a simple thing is a total turnoff for me as a user.
