Warning: if you aren't from New Zealand some of this might not make sense My (25f) nana is teaching me how to drive, bless her heart. I have read the road code very recently and I also have professional driving lessons, which she paid for, so I have a pretty good idea of the road rules and I am following them almost religiously so I have good habits for my restricted test.

There has been a few times where she has criticized my driving when I am literally just following the road code and using what I have learnt in these professional lessons. (I.e. while going straight through a roundabout, I do not indicate while approaching but as I drive past the first exit I'll indicate left as I am leaving the roundabout, as the road code says, but she doesn't think I should indicate at all) I calmly explain that to her and I even showed her in the roadcode that is what I am MEANT to do.

Tonight while driving we were driving on a roundabout (going straight) which has 5 exits instead of 4 I did EXACTLY as the road code said and she says I should have indicated right which is literally the opposite of what she has been preaching to me all those other times and I kinda slowed down a little bit, I didn't stop I just slowed down a bit (yeah i shouldn't have done that) because I was bamboozled and she literally yells at me to KEEP GOING and I left the roundabout and once again I had to explain (my tone was definitely pissed off) that this is the rules I'll even show her the roadcode again and she goes 'i don't believe you'. I was angry so I was quiet. She yells at me again when I took 1 hand off the wheel to scratch an itch. Like wtf this is normal?? As we were approaching our street I have to turn into the driveway to do a 3 point turn, and naturally when you're turning your hands aren't ALWAYS gonna be in the quarter to 3 position, at one point my hands were on the bottom of the wheel. She yells at me, this is not the first time she's raised her voice at me for this. I think it's really unreasonable for her to yell at me for that, because my hands are in the quarter to 3 position most of the time but sometimes when I'm turning my hands just end up there. I lost my shit, I said 'You fucking park, I'm not driving with you anymore. You critisize me for the most bullshit reasons.' as much as this is probably wrong, I feel justified. i am sticking to this, and I'm asking another family member to teach me how to drive instead. I know swearing at your grandmother is not a good thing to do but I'm sick of being yelled at for the stupidest reasons. I am grateful for her, I know she is on my side and it's a big deal that she is teaching me how to drive in her car, please don't think I'm not appreciative because I am. I might change my mind and feel like the biggest dick in the world tomorrow. Please humble me. I don't want validation but I want to know if I'm the asshole in this situation.

ETA: when I said I'm sticking to this, I mean not driving with her anymore.
