Would a domestic bird, one who has been born and raised in a cage or a pet shop where it is always given food in the exact place ever since birth, be able to survive if it escaped into a suburb with a fair amount of both trees and roads/cars/everything else one would find in a suburb? Even if its wings were not clipped?

It isnt just about finding food. Its more about predators which the bird may not have a natural instinct opr defense mechanisms to avoid. So many predators out there from other carnivorous birds to cats and dogs, rats and whatever carnivorous animals you have too, where you live.
if you bird has escaped the need to find it is urgent.

The bird does have a chance of survival. The monk parrots are a perfect example of escapees that were imported to the US in the 1960s as pets, then accidentally or introduced into the wild. They now live in many north eastern states! Domesticated pigeons are also found all over the world and are able to survive easily. I have also seen a few pet birds (parakeets mainly) out in the wild. However, if birds are able to subsist in large numbers, they may compete with native species, which isn't a good thing. Birds are very smart and are able to find resources. However, if it's too cold or they face an unknown predator, they may not survive. If this is your bird, good luck!!
