First of all, I did not 'honk' her, and I followed her all the way down the road. I am certainly not going to endanger a cyclist. I was just saying that I was surprised how it made me feel. And I imagine that people who don't cycle would potentially do something dangerous.

There are areas in the road that are 15% grade. She was going slower than the speed limit - riding her brakes. This is actually a private road and she does not live on it. She does hill repeats. This road is not even 2 lanes wide. The pull outs are so that cars can pass each other when going in the opposite direction. There is no room for 2 cars to pass each other without slowing down. And there is certainly no room for 2 cars and a bike. It is not very crowded, but I have had close calls with cars. That's why I don't ride on it. Since she wasn't going very fast, I think the safest thing for her to do would be to yield and let the car pass.
