I would probably rephase it as rates are more flexible.
Say you drive for exactly 100km:
For Gp A
Old scheme, you pay $73.90 (free 100km)
new scheme $32.90 (free 0km) + $40 (for 100km) = $72.90
Not much difference actually, but if you dont drive for 100km, then
the flexibility comes in, and yes, it is cheaper, in a sense not
much sunk cost.
I see it as a marketing tactic to more ultilise their cars. As for
why they don't extend this scheme to weekends (till only friday
1900 - Sat 1900) is that on weekends, they have a shortage of cars,
esp sat evenings and sun.
