This thread is an amusing display of sample bias. Only people that want to respond yes and brag about it bothering to respond.
In reality only about 2/3rds of people in the US can drive stick and almost no one owns manual cars.
I’ve never driven a manual car. I’ve had people be like “You can’t drive manual?!” and then I would respond “So are you going to teach me?” The answer is always No, of course not, not in their car (assuming they even owned a manual, which none do anymore). My parents had manual cars but sold them 10+ years before having me.
I understand how a clutch works. It wouldn’t be difficult to learn. But what reason or motivation is there to learn when almost no cars are manual? They total something like 2% of new car sales. If you’re buying something like a 718 GT4 RS or a 911 GT3 RS for maximum driving engagement that’s great, but those cars are priced for the 1% of the 1%.
Even if you had a fun car, which I do, the drive to work is stop-and-go, roads are full, even the fun country backroads are filled with traffic on weekends, forests are burned down, gas is eye-watteringly expensive if you have a slightly performant vehicle. The time to have fun driving cars was 40 years ago.
In the USA licenses are not contingent upon manual vs. automatic. No one checks what car you drive. So you would have to learn somewhere - someone around you has to own a manual car in order for you to learn how to drive one, and here simply no one does. No one in my entire extended family, none of my friends, none of my coworkers I’m friendly with, none of the 50+ cars I have any tangential access to are manual. So even if I wanted to learn, what are my options? Buy an entire car just to learn? Services like Turo won’t let you rent one unless you can drive one already.
We have Driver’s Education in high school but it involves no actual driving - there are separate paid/private courses you can take that might involve defensive driving or learning stick. I did one on controlling skids on wet or snowy pavement and demonstrating e.g. turning under braking with and without ABS. But nothing about manual.
