When my mum bought me lessons at 17 she was adamant I needed to learn manual.
It ended up being a struggle, dealing with gears took up so much of my attention it made my driving worse, took loads of lessons and 3 tests to pass. I had been biking on roads for years so probably could have passed very quickly if I'd learnt automatic instead.
My first couple of cars were manual, which now seems stupid but I didn't know any better.
Then I test drove a Nissan Leaf, and it wasn't the electric-ness that was surprising about it - it was how much easier driving was when I didn't have to deal with gears - and how much safer a driver I was as a result of having more brain power spare to pay attention to things.
I ended up getting an automatic petrol, which has been glorious, I'll never go back to manual.
IMO manual should have been phased out as the default a long time ago just to make roads safer. Most people are dumber than me, and there are tons of terrible drivers out there, it would be a dramatic improvement if all their cars were automatic imo.
The future is electric, and they're all automatic, so we'll get there eventually anyway.
There's also an argument for not even bothering, motoring is very expensive, and working remotely gets more common over time, your kids may never even own a car.
