I've been driving for years and I still make mistakes when there's a stressful person in the car with me. You need a new teacher.
I'm looking to get some additional practice from another person. However, given my relationship with my "instructor", that isn't an option. I'm hoping you can read between the lines here.
I've been trying to learn how to drive and unfortunately I suck at it. Some combination of a stressful teacher and hyperfocusing have made it very difficult to learn. My biggest problem is with the multitasking aspect. Remembering to put on the turn signal while stopping and and checking my speed and watching out for other cars, etc. It's difficult for me, I forget or miss things. One thing I was considering may possibly help is using dual n-back to boost my working memory. Does anyone have any thoughts on the likely effectiveness of this?
