#3) When in doubt, wait: If you can’t allow the bike 3 feet of space, wait to pass until you can — just as you would for any other slow-moving vehicle.

From the Los Angeles Times, How to minimize accidents between autos and bicycles, by Christie Aschwanden. Six simple tips; short and sweet. #2 would have prevented my collision with a car, except that the 87 year-old driver apparently never saw me. I wish this information was more widely understood by drivers. Hmmm….maybe a few questions on state drivers’ tests?!

I would add -
Understand that when the wind is gusting 30mph (or even 10mph) a cyclist may have a hard time holding their line. In other words, a cyclist may be dealing with weather and road conditions that drivers are unaware of….thus the 3 foot MINIMUM.
