It would have been just as effective to have something like "Hey" and then as you passed by her window yelled or even just said, watch where your going. The profanity did not prove a point or anything. The only thing it would accomplish is inspiring her to intentionally hit the next cyclist she sees.
Having said this, what really ticks me off is when a driver yells at me for just being on the road. I was riding my tandem (with 5 year old daughter). I was in the right lane of a 2 lane road (2 lanes each way) stopped at a red light. No traffic in the left lane. Some large white truck comes next to me and the driver starts yelling. "Get the **** out of the road you dumb ass." Before I had a chance to make any sort of a come-back the light turned green, but it seemed the passenger took a look and my daughter and then said something to the driver and it looked like he had an embarressed look on his face. Why can't he just let me be on the road. I know its so terrible to have fun, exercise, use less gas, and use the roads that I pay for just as much as he does.
