I am a hazard on the road

I got my driver's licence in a few months ago with almost every points. My parents think I am a good driver because of this but it isn't true. Today, I did at least three big mistakes that could have caused an accident. I want to stop driving, I can't continue for my safety and other's safety but I have no idea how to tell my parents this. They want me to drive because they want me to be independent. They don't understand the gravity of the situation because for some reason I am only a bad driver when I am not with them. My mom she said she does mistakes too but she didn't do the mistakes that I did. I really don't want to hurt someone, I should get off the road.
