The Pedestrian always has the right of way, right? What is the law in regards to people on bicycles?

I believe they must obey the laws too.
Today when my husband was turning five teens on bicycles cut him off.
Fortunately he is an experienced driver with great reflexes. If not they would be dead. This was on Richmond Avenue a major street in Staten Island.
This made me very upset.
How can I get the message out and prevent anyone from doing this?
These teens will not make it to twenty. Too many drivers don’t care.
Has this happen to you?
