Your notion that automatic transmissions “need” active cooling that they “don’t” have when in fact they do,

I'm saying that to pull heavy loads they need active cooling. And they do. They also have cooling when not designed for heavy pulling, but they don't need as much cooling because all the mechanics you literally agree with me over: More cooling is needed under heavier loads. This isn't some far-out concept it's physics, it's what happens when you put oil in essentially a blender, it gets hot.

Then, and this seems to get ignored by you: Americans aren't pulling heavy loads with cars. Why? Do you have an alternative explanation?

What’s the US spec rated tow capacity of a Crosstrek? Oh wow, it’s 1500 pounds.

1270 kg over here (with trailer brakes, 12% incline). That's nearly twice. Tongue weight: 80kg. That's less.

And that's a Japanese SUV. You can get VW Golfs with 1.8t towing capacity, that's a compact car. Also pure combustion ones, the Crosstrek is a hybrid it's easy to get low-end torque with one of those and transmission is a whole another topic.

This is because it is dangerous to tow a low tongue weight trailer at high speed. America has no such speed or tongue weight restriction, and we also have interstates with 85 MPH speed limits.

That's why trailer brakes exist and don't pretend 140km/h are fast... though with a trailer you're generally limited to 80 or 100 here, depending on make and whatnot. Maybe you should introduce speed limits, regulations for brakes on trailers, etc. Maybe you would if your small cars could even tow that much, physically. You should also start to use the left lane for overtaking only and get rid of those ludicrous amounts of stop signs and build your cities so that people can move in them, not just cars, but I'm digressing.
