Once the rider’s attention is caught, reaction time begins. Most human-factors experts put average reaction time to traffic hazards at about 1.0 to 2.0 seconds, averaging around 1.5 seconds. If you swerve, add another half-second for the time delay due to countersteering and developing the correct lean angle before your motorcycle begins to head in the desired direction. Those delays leave little or no time for evasive action to succeed. About 30 percent of riders in the Hurt study took no evasive action at all, often because there was too little time. Even highly skilled braking usually won’t do that much to delay your arrival at the crunch point. Here’s an example: Let’s say you’re going down the boulevard at the 35-mph speed limit when Joe Numbnuts turns left across your path. With reaction time and all, you’ve got one second left, so you do a highly skilled stoppie, bringing your speed down to 15 mph in that second. Your average speed during that one second was 25 mph, and you braked for 37 feet. If you hadn’t braked at all, you would have covered that 37 feet in 0.72 seconds. So your highly skilled stoppie and nerves of steel delayed your arrival at the crunch point by about a quarter of a second compared to doing nothing at all. Is that enough time for Joe to clear his big SUV out of your way? Usually not. And few riders have as much as 37 feet in which to brake. Even worse, when faced with death or a world of pain seconds away, most riders do a miserable job of braking and swerving.
