> The majority of drivers DON’T know how to change gears.

I'm not sure that's true, unless you only take certain parts of the world into consideration.

"Expert level knowledge" implies something more to me than simply few people knowing about it. It's ridiculous to say that knowing how to change gears makes you an expert driver, even if a minority know how to do it (such as in the US e.g.)

I think the idea is it shouldn't be expert level. It used to be in every tutorial. But you're right these days it may indeed be expert level knowledge
