Quick summary: my niece (18) has asked for help learning how to drive. I have no issue with this but need some help. Back in February two of her friends were in a severe accident, one didn’t make and the other is still recovering. They were not at fault, it was a drunk driver. However, my niece has expressed how this has caused her anxiety to worsen when she tries to practice driving. Which is completely understandable and she has been seeking help. She did express she didn’t like driving with her mom (my sister) because she’s not very patient. She did okay the last time we went out and has asked to try again but I want to try to help her anyway I can. 

Does anyone have any tips to help make the experience better for her or to help reduce her anxiety?
