A second drill that is inadvisable to practice on the street is the instant turn. The instant turn is a maneuver designed to give you an option on how to deal with that Escalade that just made a right turn in front of you besides going underneath it. Again, there's a very good chance it'll never happen, but if it does, someone who performs an instant turn in an emergency might be able to just have a close call. This IS a drill I do on my own, using empty parking lots. If I ever need to do it for real, I do not want to have to THINK about how to deal with the emergency. BikeEd will show the principle, but the student has to make the decision to practice, practice, practice. You don't get that from regular riding. If you're reading this blog, you're worth saving.
One last word on the instant turn. In his book, Effective Cycling, John Forester writes:
You can't safely learn the instant turn on the road, and you will never do it right without practice. ... The only time I was hit was before I learned the instant turn. A car coming the other way turned into a wide driveway. I managed to get into the driveway, but couldn't turn sharply enough to outdistance the car.
Like Forester or hate him, he has credibility when it comes to a statement like that above.
There are a number of other drills as well, but most of them will do no more than teach you how to get a bit more out of your bike, and maybe avoid flats. Those have the ancillary benefit of allowing you to get more out of your cycling, but the ones above may save your life. Even if they don't, knowing you are prepared will improve your confidence on the road just a little bit. If you're reading this blog, you're worth it.
Actually, the Bike Drills are Also Fun. In a Way, it's Like a School Bike Rodeo for Grownups
