How do I make city maps in google form?

A Vector program would be ideal here. Inkscape is free if you don't already have one. In a nutshell, you would create paths to lay out your roads and other objects and then stroke the paths with various details to get the right color/line styles.

I agree that you need a vector program for this. You should understand tho that those maps were likely generated dynamically from a data set and programatically rendered.
