I have to admit, my dad was the worst passenger in a car I had driven for him, he was on motability and I was his backup driver as he had copd and frequently had to ask me to drive.
As I am Dyslexic and Dyspraxic aswell as awaiting official tests for Aspergers and ADHD, my dad never knew this at the time, I only found out in September 2019, 2 years after dad passed but he frequently had a go at me purely because I never drove exactly how he did, even my brother often found himself on the receiving end of my dad's often harsh comments.
In the end I had to say that yes he'd had a great deal more experience than I had, but I had to point out that no matter how long you've been driving, you never stop learning as there is always somehing new to get to grips with.
Even now, 21 years after I passed my test, I still find myself learning new things, will the changes ever end, who knows.
