I did what you suggested, spent about 10 minutes looking around.
Yes, there are buildings, and yes there are cars. But, I saw hardly any cars (mainly buses, and only a handful of those), and I also didn't see any parking lots. So, either I completely missed it, or you're seeing something I'm not.
Just for kicks, I looked up a list of the world's poorest countries, and picked #1, Congo. While I don't see as many industrial/high-rise buildings in the cities (definitely many more individual homes) I see more cars and other signs of human travel and habitation.
