I believe it looks like the creation of sprawl. If you wanted this to happen, why are you in the city at all? Why not just move to the exurbs. It already exists like that there. It's another example of the car companies and traffic engineers fantasy that everyone wants a car and everyone can have a car if we just pave the city with lanes to accommodate it. It's just cleverly repackaged as a promo for GPS navigation. Fortunately, we're beginning to think differently about the roll they play.
