City suburbs within the sprawl are not 'rural', and cycling in them is just as quick as cycling in the city center. I think you are grossly overestimating the speed of a car in city suburbs and underestimating the number of delays car drivers are subject to. Also, you seem to be underestimating the ability of a cyclist to match a car's speed in that environment. Maybe you haven't tried it so you just don't believe it.
I have tried it, in cities, in suburbs and even in the countryside. I know that in suburbs and the city, a bicycle can match or beat a car's speed over a commute of up to 5 miles. In the countryside I've even beaten trains over a 30 mile stretch. The idea that trains, buses, cars are faster than bicycles is a myth. They 'can' go faster than bicycles when conditions are right, but in practice they do not because conditions in an urban commute are usually complicated, and cars, buses, trains, etc., are either hampered by built-in inefficiencies (such as having to walk and from stations and wait for a scheduled bus/train), or not flexible enough to overcome the inevitable delays.
You're gonna tell me about where I live and the sort of cities I've driven in for over a decade... Average motor vehicle speeds here are well over 20mph. Even during rush hour. The day I average 20mph in the city on my bike is gonna be a good, sweaty, day.
