USA, 40, and...it's complicated? Haha. I've never driven a manual car, but I have ridden a motorcycle which generally has a manual transmission.

And because this is as good a place as any--I suspect once self-driving vehicles are common, the number of people who can drive even an automatic will plummet.

Why? Because kids will be born, then grow up with parents driving them places for their entire life experience, and then will go into their teens using driving services (like some futuristic Lyft company) with automated driverless cars that drive for them. And if that works fine to get you everywhere you need to go...why bother to learn how to drive a car? Do you really NEED it?

I think there'll be a generational divide, with older generations boggling that the damn kids on their lawns are "so lazy" they never even learned to drive, and I think there'll be an urban/rural divide where rural kids might not have access to AI cars that can drive for them so are forced to learn in order to be able to get anywhere, while city kids can have a car summoned to them by their phone at a drop of a hat to get wherever they want to go.

But I think the younger generations, once one is born where self-driving vehicles are ubiquitous and being able to summon such a vehicle to you using your phone is commonplace (I think it'll be a generation or two after the Zoomers...we're on the horizon but not there yet), will not see why THEY have to drive when they can instead be driven. Driving is a waste of your time that you could use to be doing work, schoolwork, or something fun like a game. I know I would ditch it if I could go exactly where I need to go anytime I wanted while reading a book or something.

Edit: Self-driving cars would also be a HUGE boon to the elderly, giving them some sort of independence even once their reaction times dull. "No, grandpa, I can't let you drive yourself, but the car will totally take you wherever you need to go. Just put in your destination." There'll be a lot of bitching at first from some of the older people, then they'd figure out how easy it is to go places without worrying about their eyesight or something, and give in.

I suspect my generation might be the first in this position, of giving up keys and instead just ordering a car to take me somewhere without me being a danger of running someone over because my reaction times have degraded. I think it's reasonable to suspect in 40 years, when I'll be 80, cars will drive themselves.
