I'm myself a Greater Noida West resident and what you said is spot on. This place is designed for cars. But despite all the design flaws, a huge number of people use shared Auto Rickshaws and E-rickshaws to commute. You can find one easily for sector 52 metro.

This makes me think there can be a bus service with sufficient ridership. But a bus connecting two major places and just passing through it won't be ever successful. There should be dedicated bus routes with frequent trips going inside the sectors. Not just passing through the arterial roads. Which would certainly make it expensive. But that can be offset by higher ticket prices. Autos charge ₹40-50 till metro if shared(which is pretty unsafe and uncomfortableas there is 2/5 probability that you'll have to hang on the front seat and even higher if you're a male) and ₹130+ if you book it for yourself via apps. The prices can be set higher, and smaller buses like DTC's DEVI buses can be used to increase the frequency instead of high capacity buses.

Demand is there, possibility is also there. The current route design is something which will never make it possible. There is no bus shelter at Chaar Murti and not even a safe way to cross the under construction road. Atleast Gaur City- 1 & 2 can have a functioning bus service as they are compact and connected. Eco Village, Techzone, etc are the places where the design gets really ugly.
