I'm 58 and only passed my test 2 months ago. I still get quite severe butterflies before I enter my car especially if I am going somewhere unfamiliar. However as soon as i enter my car I go into driving mode and that fear disappears. As a new driver I accept I'm going to make mistakes but then I look at other drivers and they do too, when i do make a mistake like the old saying I learn from them which hopefully makes me a better driver in the long run
