That's not a concern for you to worry about .
Dhaka/Lahore/Karachi have similar populations and are more comparable as compared to a planned city . I don't know about you but people from abroad seem to compare it to an American suburb .

My journey began in Islamabad, the capital of Pakistan. Islamabad, meaning Abode of Islam, is Pakistan’s government and financial center. It’s an affluent city built 40 years ago at the base of the Margalla Hills. Pakistan’s capital looks more like a wealthy American suburb than the government center of a developing nation – immaculately kept tree-lined sidewalks, large forested parks, three story homes with multiple Mercedes parked out front.

ISLAMABAD, Pakistan — Much of
Pakistan’s capital city looks like a rich Los Angeles suburb. Shiny sport utility vehicles purr down gated driveways. Elegant multistory homes are tended by servants. Laundry is never hung out to dry.

In Islamabad, a quiet, artificially-planned capital, like Brasilia, Canberra or Washington, D.C., the streets are wide and many of the houses are large. The city can often look and feel like a boring American suburb. There are white grandiose stone buildings for the President, the Parliament and the Supreme Court, but there never appears to be anyone around these buildings, except for armed guards.
