Knowing how to use the brakes, gears and ride well is part of the equation, learning to predict, prepare and avoid drivers who may kill you is another. Experience is a great teacher. I watch guys fly by me and thread the needle between cars all the time. I've paid those dues. Situational awareness and experience (preparing for the worst and avoiding high risk situations) is the way to go. Those who speed around blind turns are gamblers. Ride like your life depends on it.
