I'm also teaching my daughter to drive. Fmd what a time. I didn't have an anxiety issue before I had a 16 Yr old.
Myself and my ex taught my then 16 yo to drive. She is now 18, has her red P's and drives what I would call rather competently. It was the amazing the difference between the two approaches to this driver training.
I taught my daughter in my manual Mazda BT50 work ute. A huge car AND a manual. A very difficult car for a 16 yo girl to learn on. All our lessons were calm, relaxed and beneficial to her driving skills. I took her to the industrial area around Rose Hill racecourse on Sundays, when there was little to no traffic (besides the odd large truck or petrol tanker) and we had the roads to ourselves. She learnt so much. Yes, she made some mistakes but I would point them out and encourage her to learn from them.
The ex took her straight out onto local roads in her latest BMW M3 with all the bells and whistles. My god, the amount of arguments those two got into was incredible. Absolute screaming matches. Yelling at someone who is learning to drive seemed counter-productive to me, but, it is what happened.
It got to a point where my daughter only wanted lessons from me in the more difficult car to drive simply because the lessons with her mum were so stressful.
Anyway, she is now quite a decent driver for her lack of experience. I'd like to think I was responsible for her confidence.
It's tough work teaching someone to drive but calm and patience is the best way.
