Re: THE TWO-SECOND RULE
There are no guarantees in life, but there are some strategies that work well most of the time in most situations, and the two-second rule is one of them.
An alternative to single-file group riding -- which strings out riders for miles -- and side-by-side parade riding -- which gives nobody any room to move to avoid road debris -- is staggered group riding.
Divide the lane into three sections: left, center, right. The first rider is in the left part of the lane, the next rider in the right side, then the next in the left, etc.
This alternating left/right spacing allows the lead rider to easily keep track of who's behind. It also gives each rider the width of the whole lane to move side-to-side to avoid roadkill or other debris.
To keep a safe amount of space between riders while still keeping a reasonably tight formation, have each rider watch the bike directly ahead. When the bike ahead passes a landmark, such as a utility pole, count "one-and-two-and." If you pass that utility pole before you get to the "and" of two, you need to back off. If you find yourself counting "three-and" or "four- and," you can tighten up a bit.
This keeps a two-second cushion between riders. It works at any speed. At lower speeds, the distance between riders is less. At higher speeds, the distance between riders is greater.
At 60 mph for instance, a two-second gap leaves 176 feet, or about 9 car lengths. At 10 mph, a two-second gap leaves about 18 feet.
Trying to visually determine a safe gap is nearly impossible. Using a timed interval, however, works at all speeds and automatically adjusts for speed variance.
NOTE: Everybody still has to pay attention.
