You are perfectly right. Those are the people that make motorists hate us all, and not want to share the road. Anyone who is so self-absorbed that they can't be bothered to try not to inconvenience others (on a bike, in the grocery store, .....) should try to put themselves in the other person's position.
That is an ideal way to promote a little road rage. No motorist is going to feel more kindly toward cyclists in general after an encounter like that. They make us all look bad.
