To add a little to Frank's comment, think of a multi-lane freeway. As the car number density rises the flow slows, so more lanes must be added. You can't get people to refrain from lane changing, cops tagging speeders slows the flow, collisions do the same. When the freeway has more than 12 lanes in one direction, the flow realizes an unexpected turbulence. In heavy traffic drivers can't see where the edge of the road is, so they make crazy moves to catch their exits. And you get paranoid because you're trapped in a sea of careening cars.
Each lane is like a WDM laser color. You can increase the car number density of a lane, you can try to get drivers not to change lanes with signs, and you try to educate drivers on freeway etiquette including single car strategies to promote laminar flow, but there is a limit to these strategies. QoS tries to implement diamond lanes and outside lanes for trucks to organize traffic by certain priorities. ATM tries to put cars on long flatbed trucks and haul them along so that they can't change lanes or get in accidents. Other strategies use office daily opening staggered times to alleviate bunching. At about OC-768 you have the 12 laner. You have a daily mess. You simply can't add any more lanes because people go crazy.
SR builds busses. SR builds multi-layered car delivery trucks. Either all the lanes go into one lane with n-decker car delivery trucks or the people ride busses in one lane. We haven't figured out exactly which of these techniques is being used by SR, but we are hot on the trail. Suffice it to say both these are four dimensional phenomena or need four degrees of freedom to describe. The people are taking a seat in the bus while the bus is zooming along. Or the cars are being stacked while the truck flies along. When the vehicle reaches a destination, they get off or are unloaded the way they were loaded. Trucks and busses can be n-deckered which implies something like OC 192000, and you can have traffic going both ways simultaneously in one lane without collision. That might need another degree of freedom!
