I never said that it was ever going to be perfect. I did say one could minimize the risk by following the rules and practicing defensive driving. Crashes aren't as inevitable as people make them out to be. I've avoided crashes while cycling as well as motoring by paying attention to the situation ahead and behind and proactively taking action to avoid putting myself in a situation where I would have crashed into another vehicle or been hit (e.g., seeing that drive not stopping for the red light and not driving into their path).
