I occasionally drive on major local suburban roadways. Think four lanes, direct north/south or east/west routes, speed limits of 35-45 mph, and lined with strip malls, fast food restaurants, gas stations, big box stores, and various other uses. Because of all of the traffic that wants to get on and off the road and because there are regulations about how to do this safely, such roads have regular traffic lights.
In the suburban road logic, these motorways are necessary to move larger volumes of traffic. Off these major roads are endless residential streets lined with single-family homes or small multi-family housing units. Traffic could cut through some of these neighborhoods but they have lower speed limits, narrower streets, and plenty of stop signs.
Occasionally, by finding the right time of day or the right position within the flow of traffic or finding the communities that have timed their traffic lights well, you can drive down such roads for ten-plus minutes without hitting a red light. It is smooth sailing. It is a slower but local highway. You can improve your gas mileage.
But, this is rare. During busier times, there may be too much traffic to get through each light. Late at night, the side streets might have sensors that turn their direction to green when just one car arrives. The drive becomes a series of stops and starts. Up to 40 mph, stop again, back up to 35 mpg, stop again.
Thus, when in the middle of a magical moment without stoplights impeding your path, enjoy it. Hear a few songs in a row while moving. Look at the communities as you go by. Marvel at the ground that can be covered when moving at the speed limit for more than a few minutes. Soon you will be back at a traffic light, waiting to get started again.
