That sounds like it'd be breaking some rules of some sort, if you're a terrible driver they shouldn't want to even let you out on the roads.

The teachers don't pass you, state officials who are trained to give you the test do. And if you failed, he could've just refused to teach you. legally he had the right to refuse service.

If you hit something it's an automatic fail
