If vehicles are driven safely, the following driver will allow 3 seconds between himself and the vehicle directly in front.Hmm. The one carlength per 10 mph rule that I was taught is more like 1.5 seconds. But in any case, if you allow x seconds between yourself and the vehicle in front of you, there will be one car passing every (x seconds plus the time it takes a vehicle to travel its own length). The time for a vehicle to travel its own length increases at lower speeds. I realize this is a fairly minor effect unless you get down to 10 mph or so, but it is some effect. |
