Distance based fare - an example

Here is an example of the calculation of the distance based fare - which seem to be quite complicated.

My view
It is a national habit in Singapore to do things in a complicated way and to spend (i.e. waste) tens of millions of dollars on computer systems and consultancy to manage these complexities. The distance-based fare system is the recent example. (So far, nobody has told me how many millions it cost - so difficult to get relevant information in  Singapore). In London, the fares are based on zones, and not calculated in this complicated manner.
