Why does Bangalore have such pathetic roads?

I have lives in a lot of cities, both tier 1 and tier 2. But nowhere have i seen road quality as pathetic as in Bangalore. Even remote villages in UP have better paved roads. And living in Delhi, I had almost forgotten that potholes still exist. I really want to understand how the silicon valley of India has completely failed at building even an average level road infrastructure? Is it due to corruption or something else that we don’t know of?
