Have you.... even lived in a city? You see miles of idling cars in cities... do you think those are city residents sitting in cars? Those cars are suburban commuters. People in cities don't own cars. You know that right? The whole point of living in a city is to avoid wasting hours of your life every day sitting in a car. What a depressing existence that is. And even so, the miles and miles of highway are an order of magnitude more - you just don't experience it the same way so it's hard to compare. Think about it.

It's not really debated that the carbon emissions of suburban life is an order of magnitude more than urban life. They just aren't comparable.
