I'm commenting on this because I wonder if the considerate driver may have ultimately been confused and even offended at my hesitance to just go when they were waving me on. I want/wish that they realize why I behaved the way that I did. As a cyclist, we are one of the most vulnerable users of the road, and we can not be vigilant enough with our thoughts and actions when it comes to our own safety. Even those who think they may be helping us to be safer can inadvertently put us in a compromising position.
Be aware out there, be safe, and good luck!
