Notice that the reason the code is data driven to this extent is simply because it has been automatically generated from Matlab Simulink models.

Massively popular in the car industry and it will produce code exactly like this as there is very little control flow in Simulink.

(There is of course control flow, but really only in the basic elements of blocks you are composing, like a switch or a minmax block. Here is a good example of a Simulink model:
