This is really an unfortunate problem that both pedestrians and cyclist have to deal with. There are a lot of people whom believe the car should have the right away and to heck with everyone else. You can blame many different things for this, society, the auto industry on pushing cars onto us or just the fact there are jerks in life that we all have to work with in one manner or another.
The best thing to do is to let it slide and you as the cyclist continue doing what you think is right and what makes you happy.
My Wife had a similar incident 18 years ago when she was riding to school (college). She has disliked riding bikes ever since, even if I'm with her, she just doesn't want to do it. Which I view as being sad.....she doesn't realize what she is really missing. Spending time with her husband doing something he loves is something she won't do. It's also sad that there is a $500 bike hanging in my garage not being used.
