Odd and even dates parking

I have observed in Pune and at other places in India and abroad we have parking on alternate side of the roads on odd and even dates. If the road is bidirectional without a divider then this approach makes sense. The common sense lacks when there is a divider.

In the presence of divider dividing the road (almost equally) the day there is no parking on the side of the road the road will have more usable space while the other side of the road will have less space.see the image below to see if it makes sense.... Comments welcome
