Mumbai Traffic Police — Please clarify the speed limit on mumbai pune Express highway

Address:

Mumbai

What is the use of EXPRESS Highway if we have to drive in such slow speed like city traffic. Is this the way the govt get collect money on such stupid fine?
We pay income tax toll tax and this stupid or irrelevant( we had 75 speed ) fines because of this govt rules. My question is what is the use of so called "EXPRESS highway " if we dont have atleast 100 speed limit? And where are the boards of those speed limits? Do we drive the vehicle or read those somewhere outside behind the trees boards?? I request you to please ye logose faltoo rules banake paisa mat mikalo. It is not affordable. Agar nikalne he paise to vo proper board vagera lagane ke liye bhi use karo.
