Ah I see! You see I am also American and have an automatic, but don't have the funds or space for boats, caravans, or horses. I definitely did not know that about the torque converter, so thank you for that info!
I guess I just always assumed that those with the money and land for those activities you listed are wealthy enough to be in the extreme minority, but the way you say this makes me think my friends across the pond have a different perspective. Perhaps I am also in a bit of a bubble, having grown up in and only talk to people in a similar economic class.
