To keep those skills warm and ready to use, I play a game while riding I call Worst-Case Scenario. It's pretty simple, really. In every traffic situation I find myself in, I envision the worst-possible things that could happen and come up with a plan to deal with them. Maybe it's an oncoming car turning left in front of me over the double-yellow; or the Starbucks Swerve; or an emergency stop by the car in front of me; or maybe a suddenly appearing foot-deep pothole. Whatever. Funny thing is, once in a while even the craziest, stupidest things you can imagine actually happen. And when they do, you'll be ready if you're playing the game.
