Or does your commute occur at 11pm and you only use the highway to travel 1 exit?

The specifics of that technique would be fascinating. Do you set it at 45 mph and stay in the L lane?

You can’t get much more constant than that.

That’s leaning toward the constant velocity fallacy.

Many if not most motorists hit the road every time expecting traffic to flow at a constant velocity, but it never does for long, and they’re as guilty as anyone.

Maintaining a constant velocity is not a skill many people practice once they are licensed. They tend to teach themselves to follow at a constant distance/close distance instead, which teaches them to not maintain a constant velocity, even though they still think they do, because they once ‘learned’ to.

That said, a monster following distance can be attained 90% of the time by operating at the speed limit. That way you don’t have to immediately react to every tiny traffic speed fluctuation. Then, the trick is to adjust your velocity early, in tiny increments, in response to what traffic is doing as far in the distance as you can see.

There is no need to slow down unless the traffic in front of you slows for some reason. If everyone follows at a safe distance there should be no reason to slow down.

Speeding is what often leads to saturation when otherwise there would be plenty of room. Oddly enough, many drivers who maintain the minimum “adequate” following distance and refrain from tailgating will take your bumper off after passing.

In Montana, where they “sand” instead of salt the roads, this habit of many showers your windshield with gravel, and there may not be another vehicle in sight in either direction for 3 miles.

I once had my windshield replaced and didn’t make it to 10th gear before one of those showers busted it again.

The problem with traffic slowing down to maintain distance is that there are too many motor vehicles per given mile of roadway, the foundation of this article, but nothing seems to change that.
