You see a hole open up in traffic in the next lane. To capitalize on it calls for re-aiming the bike and a brisk roll-on, but assessing the surrounding traffic takes too much time, and the moment to act decisively is lost. Indecision shrinks a 20-foot opening to 15 feet—still enough room to make it, but now it requires even greater acceleration. As that window of opportunity is passing, brake lights turn the cars ahead into potential hazards. Roll off, touch the brake lever, and adjust your steering to line up the bike in your lane once again. The car in front of you looks too close, so you lag a bit longer to make some space, prompting a look in the mirror. The car behind you is closing up. Gas it? Brake? Change lane position? Do all three? Whenever two or more actions or ideas overlap in importance, one—or all—will suffer in the crossfire of indecision.
